Nazi eugenics is one of the main historical events influencing current popular as well as scholarly discussions of reproductive genetics. This influence, however, is open to different interpretations and social constructions. Based on 44 open interviews with Israeli and German genetic counselors, conducted in 2000–2003, our findings suggest that while the majority of German counselors reflected on Nazi eugenics as setting moral limits for contemporary repro-genetics, many Israeli counselors detached their contemporary practice from the wrongdoings of the past. Correspondingly, German counselors were far more sensitive towards the disability critique of repro-genetics than their Israeli counterparts. We conclude with a discussion of these two opposite positions, suggesting that the comparison of German and Israeli professionals reveals a profound complexity and involvedness in coming to terms with the “eugenic” lessons of the Holocaust, on both sides. In Germany, potential benefits of repro-genetics might be rejected due to an emphasis on a more universalistic lesson of the Holocaust regarding the value of human life and dignity. In Israel, a more particularistic lesson of the Holocaust regarding national Jewish survival, combined with a lack of public debate regarding medicalization and geneticization, might have promoted the advent of unregulated commercially and consumer-driven repro-genetics.  相似文献

Abstract

Observations of client‐counselor interaction during genetic counseling sessions at a metropolitan hospital on the West Coast identified five major problems with which genetic counselors had to deal. Their clients needed: (1) a diagnosis of the disease condition; (2) an evaluation of the genetic nature of the condition; (3) to be taught biomedical information; (4) assistance in coping with psychological stress; and (5) information on available community resources and social service support. The genetic counselors under observation tended to satisfy the clients’ first two needs, the need for a diagnosis and for a genetic evaluation, but they tended not to satisfy the clients’ needs in the areas of education and psychosocial counseling. Genetic counseling appears to demand a synthesis of five different professional skills, those of the medical doctor, the geneticist, the educator, the psychotherapist, and the social worker. These findings are discussed in terms of their relevance for creating programs for training genetic counselors.  相似文献

The first training program for genetic counselors began in 1969. Since then a number of other programs have been developed and more than 650 individuals have graduated from these programs. This article reviews the development and current status of training opportunities for genetic counselors. Twelve programs that currently grant a master's-level degree in genetic counseling are reviewed. Other areas, such as certification and licensure, that reflect genetic counseling training or such issues of professional growth as continuing education and career advances are addressed.  相似文献

Many social scientists and commentators have expressed concerns about the acceleration of genetic medicine and testing in the last few decades. While there is a growing body of work on how patients and the lay public view the potential of genetic medicine, there remains relatively little social science research on the personal and professional views of master's-trained genetic counselors, a growing profession of clinicians who are often the key medical actors translating increasingly complex genetic information to patients. This study begins to fill in this lacuna by examining the perspectives of 26 genetic counselors in the USA on some of the central bioethical concerns raised by genetic testing, with a particular focus on prenatal testing. The study finds that while there is general enthusiasm for genetic medicine, and prenatal testing in particular, genetic counselors also have reflexive ambivalence, expressing both skepticism and concern about the usefulness and consequences of acquiring genetic information.  相似文献

A statistic is introduced that relates discoveries made in genome-wide association (GWA) studies to patterns of disease risks among relatives. The genotype-specific recurrence risk (GSR) is the genotype-specific risk to relatives of known relationship to affected probands. The GSRs can be used for three purposes. (1) They can provide an independent test of whether an allele identified in a GWA study is associated with the disease. (2) They can provide a test of whether interactions among loci affecting the disease are multiplicative. (3) They can be used by genetic counselors to incorporate information from GWA studies for predicting the risk to relatives of known genotype. Under a multiplicative model of disease causation, the GSRs for a locus are the genotypic risks in probands for that locus multiplied by lambda(R)/lambda(jR), where lambda(R) is Risch's recurrence risk ratio and lambda(jR) is the contribution to lambda(R) from the locus of interest. If there is saturation of risk with increasing numbers of causative alleles, then observed GSRs for individuals with high-risk genotypes will be lower than predicted by the multiplicative model.  相似文献

In 1998, Foster and colleagues published the results of a genetic study intended to test whether Thomas Jefferson could have fathered any of Sally Hemings' children. They found that the Jefferson Y chromosome haplotype matched that of a descendant of Hemings' youngest child, but not that of the descendants of the eldest son, Thomas Woodson. The Woodson descendants were shocked by the study's finding, which disagreed with their family oral history. They were suspicious of the study conclusions because of the methods used in recruiting participants for the study and the manner in which they learned of the results. The Woodsons' experience as participants in one of the first examples of genetic genealogy illustrates several issues that both geneticists and amateur genetic genealogists will face in studies of this kind. Misperceptions about the relationship between biology and race, and group genetics in general, can make the interpretation of genetic data difficult. Continuing collaborations between the media and the scientific community will help the public to better understand the risks as well as the benefits of genetic genealogy. Researchers must decide prior to beginning their research what role the human subjects will play in the study and when they will be notified of the study's conclusions. Amateur genetic genealogists should anticipate unexpected outcomes, such as the identification of nonpaternity, to minimize any harmful effects to study participants. Although modern genetic methods provide a powerful new tool for genealogical study, they cannot resolve all genealogical issues, as this study shows, and can involve unanticipated risks to the participants.  相似文献

Mass media coverage of genetic engineering is considered as an essential cause of the public image which this technology has. Because most people have only few experiences with this technology, the influence of journalists, who report on genetic engineering, seems to be obviously high. Which attitudes do these journalists have? How do they inform themselves? These and other questions are to be answered by a standardized survey among German journalists. For the first time the results of this study reveal the methods of investigation and source selection of 'genetic engineering journalists' and afford an insight into the journalistic climate of opinion on genetic engineering and its applications. There is clear evidence of an altogether positive global judgement of journalists reporting on this technology, which finds support in their immediate professional social environment.  相似文献

As part of a multicenter study supported by the German Mildred Scheel foundation we have established an interdisciplinary counseling setting for members of breast and/or ovarian cancer families. We offer simultaneous counseling by a team consisting of a geneticist, a gynecologist and a psycho-oncologist. Here we describe our counseling protocol and our first short-term experience with this interdisciplinary approach. Preliminary data on patient perceptions and behaviors in the context of DNA testing are reported. Overall, our counseling approach was perceived as beneficial both by the counselors and the consultants. A marked overestimation of the risk to develop breast and/or ovarian cancer was noted in the group of unaffected individuals from medium to low risk breast cancer families in contrast to an appropriate risk perception in members from high risk families. All participants shared many of the same expectations about genetic testing and counseling and appeared to base their decision-making about testing on the risk classification given by the genetic counselor. The reported participation in gynecological cancer prevention programs was high in all families at risk, but was less sufficient in unaffected as compared to affected persons. Although current data on BRCA1/BRCA2 mutation analyses render testing in medium to low risk individuals questionable, our findings emphasize the importance of genetic counseling and education in all risk categories of breast and/or ovarian cancer families.  相似文献

Loss of heterozygosity (LOH) of the wild-type allele by structural chromosome aberrations (SCAs), homologous mitotic recombination (HMR) or intra-chromosomal (deletion/amplification) recombination (ICR) plays a crucial role in multistage carcinogenesis. We describe here an in vivo system, enabling the detection of all three chromosome breakage-related events in the same genetic experiment, with eye tissue of Drosophila as targets. This modification of the white/white(+) system enables to measure, simultaneously, HMR and ICR on the X-chromosome, and loss of a ring-shaped X-chromosome, utilizing the eye color gene white. Optimal conditions for the detection and quantification of SCAs (ring-X loss) compared to HMR are discussed in detail. Emerging new techniques comprise the parallel detection of HMR on chromosomes X and 3, using the tumor suppressor gene warts in addition to the X-linked marker white. Another modification of the white/white(+) system measures, again in parallel, HMR and chromosome duplication (non-disjunction).  相似文献

Conservation genetics is important in the management of endangered species, helping to understand their connectivity and long‐term viability, thus identifying populations of importance for conservation. The pond bat (Myotis dasycneme) is a rare species classified as “Near Threatened” with a wide but patchy Palearctic distribution. A total of 277 samples representing populations in Denmark, Germany, Latvia, Hungary, and Russia were used in the genetic analyses; 224 samples representing Denmark, Germany, and Russia were analyzed at 10 microsatellite loci; 241 samples representing all areas were analyzed using mitochondrial D‐loop and cytochrome B sequences. A Bayesian clustering approach revealed two poorly resolved clusters, one representing the Danish and German groups and the other the Russian group. However, significantly different pairwise FST and DEST estimates were observed between the Danish and German groups and between the Danish and Russian groups suggesting a recent population structure. These conflicting results might be attributed to the effect of migration or low resolution due to the number of microsatellite markers used. After concatenating the two mitochondrial sequences, analysis detected significant genetic differentiation between all populations, probably due to genetic drift combined with a founder event. The phylogenetic tree suggested a closer relationship between the Russian and Northern European populations compared to the Hungarian population, implying that the latter belongs to an older ancestral population. This was supported by the observed haplotype network and higher nucleotide diversity in this population. The genetic structuring observed in the Danish/German pond bat stresses the need for a cross‐border management between the two countries. Further, the pronounced mtDNA structuring, together with the indicated migration between nearby populations suggest philopatric female behavior but male migration, emphasizes the importance of protecting suitable habitat mosaics to maintain a continuum of patches with dense pond bat populations across the species' distribution range.  相似文献

Sloe (Prunus spinosa L.) is a shrub native to Europe. In Germany, 50–80 % of all planted sloe is imported. Little is known about the genetic diversity patterns within and between German sloe populations. Thus, a debate arose how to avoid risks for nature and landscape by planting potentially maladapted material. The main objectives of our study are to analyse the genetic differentiation pattern of sloe populations in Germany, to identify geographic/genetic structures and to evaluate their potential for tracing reproductive material. 17 natural populations from Germany and 1 from Italy and Hungary were investigated by Amplified Fragment Length Polymorphisms (AFLP) and PCR–RFLP techniques. The AMOVA analyses based on AFLPs for all populations and for the German populations only result in equally high differentiation values of ΦPT = 15 % of molecular variance between populations. The analysis of cpDNA PCR–RFLPs resulted in 24 haplotypes with 30 % showing genetic variation between populations. Overall values of genetic variability over all loci and populations are: Na = 0.832, Ne = 1.114 and He = 0.072. Mantel tests for AFLPs and cpDNA haplotypes reveal no association between geographic and genetic distances between populations as a result of a lack of differentiation between German populations and those from southern and southeastern Europe. Weak geographic/genetic patterns were observed on a large scale. However, these concern the German populations only. Our results indicate that vegetative regeneration in combination with founder effects may influence the level of differentiation between populations. Populations with a large amount of vegetative propagation are more differentiated from other populations than those populations which exhibit less vegetative regeneration. The assignment of reproductive material (i.e. plant material) to potential source populations resulted in high values of correct allocations. Hence, such methods can be applied to trace reproductive material of unknown origin.  相似文献

This article considers counterhegemonic sacrifices as a means of social intervention, and in doing so explores the social efficacy of non-ritual sacrifice in the modern era. Ethnographically, this article examines the way Israeli conscientious objectors succeed in having their refusal of military service and the social costs they incur understood as sacrifices by the Israeli public. Ex-soldiers accumulate social capital in light of public perception that they have ‘paid the price’ for their beliefs. Other ethnographic contexts that further elucidate the ability of socially abject to use sacrifice to counterhegemonic effect are presented. I claim that the recognition of sacrifice depends on an intersubjective combination of sacrificial intention and community recognition. This article suggests that the meaning of sacrifice is determined by how sacrifice is used and understood in social context, and as such breaks ranks with literatures on sacrifice concerned with the intrinsic coherence of ritual sacrifice.  相似文献

In aquaculture, cultured fish often undergo continuous cross-fertilization without any inflow of new broodstock. This lowers genetic diversity, leading to increased disease rates and decreased survival rates. To improve the mass production and easy culture of Israeli carp, it is essential to investigate the population structure and genetic diversity of these fish. However, such a survey has not yet been performed on Korean Israeli carp. In this study, we used seven microsatellite markers to analyze the genetic diversity and association of cultured Israeli carp from Korea and China. The average numbers of alleles per locus (N A ) for two Korean (KorA and KorB) and two Chinese (ChA and ChB) populations were as follows: KorA (10.42), KorB (14.43), ChA (20.57) and ChB (20.71). The expected heterozygosity (H e ) ranged from 0.672 to 0.897 and from 0.827 to 0.938 in the Korean sample and Chinese sample respectively. The genetic diversity of the Korean Israeli carp was about half that of the Chinese carp. The diversity of the Korean Israeli carp was very low, suggesting that the immunity of this population could be weak, and that diversity–recovery studies are urgently needed. Therefore, our results may therefore form the foundation for future research efforts towards genetic monitoring and selective breeding, continuous research needs to be conducted in order to recover the genetic diversity of the Korean Israeli carp.  相似文献

Expansion of CAG trinucleotide repeats has been shown to cause a number of autosomal dominant spinocerebellar ataxias such as SCA1, SCA2, SCA3/MJD, SCA6, and SCA7. These disorders are characterized by a wide inter- and intrafamiliar variation in clinical features. The same mutation can result in different phenotypes and the very similar phenotypes can be caused by different mutations. Therefore it is necessary to investigate more SCA genes (according to prevalence) to identify the causal elongation. We developed a fast and efficient screening method based on touchdown multiplex PCR with fluorescent labelled primers for the most common types of SCAs (SCA 1, 2, 3, and 7). It has been reliable in 113 probands tested. Fragment analysis was performed by using 6% denaturing polyacrylamide gel and employing the automated DNA sequencer. This method considerably shortens the process of molecular genetic screening of SCAs and might be used as a tip for designing other SCA screening sets.__________From Genetika, Vol. 41, No. 6, 2005, pp. 830–837.Original English Text Copyright © 2005 by Bauer, Kotliarova, Matoska, Musova, Hedvicakova, Boday, Tomek, Nukina, Goetz.The article was submitted by the authors in English.  相似文献

A successful control or eradication programme using biological control or genetically-mediated methods requires knowledge of the origin and the extent of wasp genetic diversity. Mitochondrial DNA variation in the native and invaded range of the social wasp Vespula germanica was used to examine intra-specific genetic variation and invasive source populations. We also examined wasps for the presence of four viruses found in honey bees: Acute bee paralysis virus, Deformed wing virus, Israeli acute paralysis virus and Kashmir bee virus. German wasps showed reduced genetic diversity in the invaded range compared to that of their native range. Populations in the introduced range are likely to have arrived from different source populations. All four viral honey bee pathogens were found in V. germanica, although they varied in their distribution and strain. Multiple introductions of German wasps have occurred for most invaded regions, though some populations are genetically homogenous. The differing locations of origin will guide researchers searching for biocontrol agents and the reduced genetic diversity may make these wasps a potentially viable target for control via gene drives.  相似文献

Studies of transnationalism typically frame it in opposition to the entrapping effects of borders. Yet, for many people, transnationalism is negotiated in contexts marked by forced separation and differential mobility. Drawing on long-term fieldwork among West Bank and Israeli Palestinians, this article explores transnational ties and orientations in relation, not in opposition, to the entrapping effects of borders. Specifically, I examine the two-way traffic in emotions and perceptions that marks family, social and symbolic relationships between West Bank and Israeli Palestinians. I show how entrapping and transnational processes combine to generate a tense interplay between closeness and distance, solidarity and estrangement. The paper calls attention to complex transnational formations among people prone to entrapment such as detained and deported migrants, refugees and minorities divided by rigid borders, and it suggests that a focus on emotions and perceptions is critical if we are to understand such formations.  相似文献

Attitudes of genetic counselors: a multinational survey.   总被引:7,自引:5,他引:2       下载免费PDF全文
Of 1,053 medical geneticists in 18 nations 677 (64%) returned questionnaires on their views on the importance of seven goals of genetic counseling, the appropriateness of five directive/nondirective approaches to counseling, and their choices of action in four situations involving directive/nondirective counseling. The majority (92%-94%) regarded nondirective approaches as appropriate; their views on both goals and approaches were similar to those reported in an earlier survey of 205 genetic counselors in the United States. In clinical situations involving presentation of reproductive options to carriers of disorders not diagnosable prenatally, 74%-85% would present contraception, sterilization, taking one's chances, artificial insemination donor (AID), or adoption as options even if not asked; 66% would present in vitro fertilization (IVF) with a donor egg; and 46% (67% in the United States) would present surrogate motherhood. In regard to three situations involving fetuses with low-burden disorders (Turner syndrome, XYY, and a possible small neural tube defect), 84%-88% would counsel nondirectively. Stepwise logistic regression analyses on professional and personal background variables showed that gender was related, cross-nationally, to self-reported directiveness in counseling, with men more likely than women to regard directive approaches as appropriate, more likely to give advice about fetuses with low-burden disorders, and more likely to present either IVF with donor egg or surrogate motherhood as options. Social and ethical implications of this widespread acceptance of nondirective counseling are discussed.  相似文献
