摘要： 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.
