成骨不全显性遗传一家系五代28例报告

对成骨不全先证者上溯5代372人进行家系调查,发现该家系共有28例成骨不全,其中已死亡10例(成人、儿童各5例),均非死于本病;现生存18例(成人12例、儿童6例)。该28例均身材矮小、身高显著低于同龄正常者;均有蓝色巩膜;符合常染色体显性遗传缺陷的结缔组织病。现存活18例中,耳聋、听力下降6例;骨折9例(22例次),对照文献中分型标准,本组28例与Ⅰ型、Ⅲ型的部分临床特征相符,是否系介于Ⅰ型、Ⅲ型之间的亚型,有待于进一步研究。 Abstract:A pedigree investigation was carried out on 372 relatives in five generations of a proband of osteogenesis imperfecta.The results showed that there were 28 patients in the family.10 of them died from other causes(5 adults and 5 children respectively).Other 18 cases are alive(12 adults and 6 children respectively).The height of the 28 cases were significantly lower than those of the same age.Furthermore,they all had blue scleras.Their clinical manifestations conformed to those of autosomal dominant hereditary connective tissue disease.Among the living 18 cases,6 suffered from deafness or hearing loss and 0 suffered from fracture(22 person-time altogether).According to the classification criteria in the literature,the clinical manifestations of the 28 cases conformed to those of type I and type III,It is necessary to study further whether they belonged to the subtype between type I and type III.

X连锁隐性遗传性Marinesco-Sjögren综合征一家系五代11例报告

报告一个Marinesco-Sj?gren综合征(MSS)的大家系.通过家系调查和查体发现MSS患者11例,均为男性,已死亡7例,死亡年龄为15～20岁.患者均具有先天性白内障,智能发育迟滞、小脑性共济失调及骨骼畸形等征候.存活4例还伴有FSH水平增高,LH及T水平降低.结论认为该MSS家系为X连锁隐性遗传。 Abstract:A big family of Marinesco-Sjögren Syndrome with X-Linked recessive inheritance is reported in the paper.We discovered 11 Patients with MSS by family line inheritance and somatoscopy.These Patients were aged from 15 to 20 years old when they died with clinic feature of congenital cataract,mental retardation,cerebellar ataxia and skeleton deformity;4 patients survived,but showed high level of FSH plasme and low level of LH and T.is concluded that this is a MSS family X-Linked recessive inheritance.     

遗传性牙龈增生症的调查

本文报告了一个牙龈增生症家系的调查结果。牙眼增生症是以牙龈广泛围的增生肥大为特点的罕见病。共调查37人,发现典型患者9人〔男5例、女4例）,其遗传方式符合常染色体显性遗传。     

一个短指(趾)少指(趾)节畸形家系的调查

本文报道了一短指(趾)少指(趾)节畸形苗族家系的调查结果。该家系中患者双手、双足第一指(趾)近节指(趾)骨变短粗,第二、三、四、五指(趾)中节指(趾)骨缺如,属于遗传性短指(趾)畸形的BellA-1型。患者手纹与贵州正常苗族人有较大差异。该家系父系正常,母系4代共调查75人,发现患者22人(男13人,女9人)。系谱分析表明,该畸形属常染色体显性遗传。     

一个常染色体显性遗传先天性眼外肌 纤维化家系A

为寻找疾病相关基因,通过随访调查、体检、病理检查等手段,发现了一眼外肌纤维化家系4代中有15人患有眼外肌纤维化综合征,主要表现先天性上眼睑下垂、下颌上举、头后仰、双眼固定下转位和被动牵拉试验阳性,眼外肌病理检查结果为肌纤维化和玻璃样变性,所有阳性体征者除眼球运动限制程度有区别外,其他眼部症状基本相同。遗传分析表明,该疾病属常染色体显性遗传。该家系可作为寻找眼外肌纤维化疾病相关基因的宝贵资源。Abstract: To discover novel disease genes, a family with congenital fibrosis of the extraocular muscle was studied by a follow-up investigation, eye examinations and histo-pathological examination. There were fifteen cases suffering from congenital general fibrosis syndrome in four generations. They have congenital blepharoptosis, head tilt, chin lift, primary gaze fixed in a hypo- and exotropic position. The diagnosis is confirmed with positive forced duction testing in the affected eye. Furthermore, fibrosis of the extraocular muscles and hyaline degeneration was confirmed by histo-pathological examination. Except for different levels of restriction of the eyeball movements , other eye symptoms in positive patients are substantially identical. The genetic analysis showed that this disease was caused by autosomal dominant inheritance. The pedigree may be precious resource candidate for discovering disease gene related with congenital fibrosis of the extraocular muscle.

Congenital Hypofibrinogenemia in Five Members of a Family

The bleeding tendency in five members of one family with fibrinogen levels ranging from 58 mg. % to 158 mg. % was mild and chiefly related to dental extractions. Abruptio placentae in one patient produced severe bleeding. Reports of menstrual bleeding patterns in patients with defects of hemostatic mechanisms suggest that normal platelets, vascular function and extrinsic and possibly intrinsic coagulation systems, except for fibrinogen, control menstrual blood loss. An autosomal dominant gene with variable penetrance may determine fibrinogen levels.
