【摘要】：目的探討脊髓小腦共濟失調7型(SCA7)家系的臨床表現(xiàn)及遺傳規(guī)律。方法收集一臨床診斷為SCA7家系的臨床資料,分析基因型與表型之間的關系。結果確診該病例為SCA7家系;其主要特征為視覺障礙、共濟失調、眼球運動受限等。結論 ATXN7基因中堿基對CAG異常重復擴增為SCA7的發(fā)病原因,且與臨床表現(xiàn)有密切關系。
[Abstract]:Objective to investigate the clinical and genetic characteristics of spinal cerebellar ataxia type 7 (SCA 7) pedigree. Methods the clinical data of a SCA7 family were collected and the relationship between genotype and phenotype was analyzed. Results this case was confirmed as SCA7 pedigree with the main features of visual impairment, ataxia, limited eye movement and so on. Conclusion the abnormal repeat amplification of base pair CAG in ATXN7 gene is the cause of SCA7, and it is closely related to clinical manifestation.
