Vitamin D deficiency in undifferentiated connective tissue disease

Osteoporosis and disorders of bone fragility are highly heritable, but despite much effort the identities of few of the genes involved has been established. Recent developments in genetics such as genome-wide association studies are revolutionizing research in this field, and it is likely that further contributions will be made through application of next-generation sequencing technologies, analysis of copy number variation polymorphisms, and high-throughput mouse mutagenesis programs. This article outlines what we know about osteoporosis genetics to date and the probable future directions of research in this field.     

Putting the "landscape" in landscape genetics

Landscape genetics has emerged as a new research area that integrates population genetics, landscape ecology and spatial statistics. Researchers in this field can combine the high resolution of genetic markers with spatial data and a variety of statistical methods to evaluate the role that landscape variables play in shaping genetic diversity and population structure. While interest in this research area is growing rapidly, our ability to fully utilize landscape data, test explicit hypotheses and truly integrate these diverse disciplines has lagged behind. Part of the current challenge in the development of the field of landscape genetics is bridging the communication and knowledge gap between these highly specific and technical disciplines. The goal of this review is to help bridge this gap by exposing geneticists to terminology, sampling methods and analysis techniques widely used in landscape ecology and spatial statistics but rarely addressed in the genetics literature. We offer a definition for the term "landscape genetics", provide an overview of the landscape genetics literature, give guidelines for appropriate sampling design and useful analysis techniques, and discuss future directions in the field. We hope, this review will stimulate increased dialog and enhance interdisciplinary collaborations advancing this exciting new field.

Psychiatric Molecular Genetics and the Ethics of Social Promises

A recent literature review of commentaries and ‘state of the art’ articles from researchers in psychiatric genetics (PMG) offers a consensus about progress in the science of genetics, disappointments in the discovery of new and effective treatments, and a general optimism about the future of the field. I argue that optimism for the field of psychiatric molecular genetics (PMG) is overwrought, and consider progress in the field in reference to a sample estimate of US National Institute of Mental Health funding for this paradigm for the years 2008 and 2009. I conclude that the amounts of financial investment in PMG is questionable from an ethical perspective, given other research and clinical needs in the USA.     

From genes to ecosystems: a genetic basis to ecosystem services

Ecosystems provide services, many of which are regulated through species interactions. Emerging research in the fields of community and ecosystem genetics indicate that genetic variation in one species can influence species interactions and affect subsequent patterns of energy flow and nutrient cycles. Because there can be a genetic basis to community- and ecosystem-level processes, evolutionary processes that alter standing genetic variation can have extended consequences that matter to patterns of biodiversity and ecosystem function that exist on the landscape. Here we explore some emerging areas of research in the field of community and ecosystem genetics and discuss the general importance of this approach to evolutionary ecology.     

Chemical genetics: exploring and controlling cellular processes with chemical probes.

The new field of chemical biology brings together chemists and biologists who are seeking to understand and mimic the natural world. One research strategy in this new field is the development of biologically active small molecules as molecular probes. This approach, which has been called 'chemical' genetics, has allowed elucidation of several pathways that have been difficult to study using traditional genetic approaches.

The forty years of medical genetics in China

Medical genetics is the newest cutting-edge discipline that focuses on solving medical problems using genetics knowledge and methods. In China, medical genetics research activities initiated from a poor inner basis but a prosperous outer environment. During the 40 years of reform and opening-up policy, Chinese scientists contributed significantly in the field of medical genetics, garnering considerable attention worldwide. In this review, we highlight the significant findings and/or results discovered by Chinese scientists in monogenic diseases, complex diseases, cancer, genetic diagnosis, as well as gene manipulation and gene therapy. Due to these achievements, China is widely recognized to be at the forefront of medical genetics research and development. However, the significant progress and development that has been achieved could not have been accomplished without sufficient funding and a well-constructed logistics network. The successful implementation of translational and precise medicine sourced from medical genetics will depend on an open ethics policy and intellectual property protection, along with strong support at the national industry level.     

Medical and human genetics 1977: trends and directions

Our field is in a rapid state of evolution. The broader concerns of human genetics not of immediate medical interest such as behavioral genetics are often investigated by persons not trained or identified as human geneticists. Both medical genetics and human genetics in general have prospered when various biologic techniques have been applied to genetic concepts. A search for novel biologic methods may provide new insights and may bridge the gulf between Mendelian and biometric approaches in studies of behavior and of common diseases. Medical geneticists need to broaden their fields of interest to encompass other fields than those of pediatric interest alone. We need to attract more basic scientists. Our field is evolving from a largely research oriented science to a service-oriented specialty. This logical development is a sign of increasing maturity and makes available to the public the results of our research. The resulting stresses and strains need careful watching to prevent their slowing the momentum of our science which can contribute continued insights into the many problems of behavior, health, and disease.

On applications of landscape genetics

Recent assertions in the literature (e.g., Keller et al. 2015) suggest that landscape genetic research has been infrequently applied by practitioners. We were interested to test this assertion, which is difficult to assess, since applications may not be detectable through searches of peer-reviewed literature. Producing publications may not be a goal of practitioners. We developed a method to search the internet for evidence of research applications and evaluated 25 different research fields in the natural sciences. We found that fields with more publications also had more applications, but the field of landscape genetics was less applied than expected based on the number of peer-reviewed publications—only about 4 % of landscape genetics articles were applied. In fact, all research fields in genetics or evolutionary biology were under-applied compared to ‘whole organism’, ecological research fields. This result suggests the lack of applications in landscape genetics may be due to a systemic under-application of genetics research, perhaps related to a lack of understanding of genetics by practitioners. We did find some evidence of landscape genetic applications however, which we sorted into 5 categories: (1) identification of evolutionarily significant units for conservation, (2) managing pathogens and invasive species, (3) natural heritage systems planning, (4) assessing population status, and (5) restoration of populations.     

Who should fund and control the direction of human behavior genetics? Review of Nuffield Council on Bioethics 2002 Report,Genetics and Human Behaviour: the Ethical Context

In this ( Nuffield Council on Bioethics 2002) , the third in its series on ethics and related issues in genetics (see also Nuffield Council on Bioethics 1993 and Nuffield Council on Bioethics 1998) , the Nuffield Council has focused on four 'normal' behaviors; intelligence, personality, antisocial behavior and sexual orientation. This is a narrow range of behaviors and one where their discussion of the potential impact of predictive genetic testing is probably inappropriate. They also take an unduly narrow view of the purposes of behavior genetics in the 21st century. It is not simply to estimate heritability but to understand more about the structure of behavior and the processes which underlie it. Their narrow focus and their negative approach to the history and achievements of genetics is reflected in their less than positive support for future behavior genetic research. Behavior geneticists need to do more to publicize what their field has achieved in order to counter the very extensive antibehavior genetics initiatives which are almost unique in science. At the same time, organizations such as the Nuffield Council need to consider carefully the impact their deliberations may have on research funding.

WinPop 2.5: software for representing population genetics phenomena

The curriculum for genetics courses is shifting from a classical to a more molecular genetics focus, increasing the importance of subjects such as population genetics. Population genetics is a computational and statistical field that requires a good understanding of the nature of stochastic events. It is a difficult field for biology students with a limited mathematical background and there is a need for visualisation tools to facilitate understanding by the use of practical examples. WinPop provides students and researchers with a visual tool to allow the simulation and representation of population genetics phenomena. WinPop is a user-friendly software meant for use in population genetics courses and basic research. WinPop 2.5 contains six different modules that represent and simulate population genetics models. Genotype and allele frequencies are calculated under the different models: panmixia, genetic drift, assortative matings, selection, gene flow and mutation. The program's interface presents information in Cartesian graphics and isosceles triangular coordinate systems, allowing the user to save graphical and textual data output from the simulations. WinPop is developed in Visual Basic 6.0 and uses Windows 95 and higher. WinPop 2.5 can be downloaded from http://www.genedrift.org/winpop.php.     

Recent Developments in Human Behavioral Genetics: Past Accomplishments and Future Directions

The field of behavioral genetics has enormous potential to uncover both genetic and environmental influences on normal and deviant behavior. Behavioral-genetic methods are based on a solid foundation of theories and methods that successfully have delineated components of complex traits in plants and animals. New resources are now available to dissect the genetic component of these complex traits. As specific genes are identified, we can begin to explore how these interact with environmental factors in development. How we interpret such findings, how we ask new questions, how we celebrate the knowledge, and how we use or misuse this knowledge are all important considerations. These issues are pervasive in all areas of human research, and they are especially salient in human behavioral genetics.
