Methods: Twelve exons of the LMNA gene were amplified from genetomic DNA. PCR products of each exon were analyzed by single strand conformational polymorphism (SSCP). Results: No abnormal SSCP pattern, suggesting no mutation in our CMT patients, was detected. Conclusion: The CMT diseases resulted from the mutations of LMNA gene were rare.展开更多
目的探讨LMNA相关的先天性肌营养不良症的临床特征和诊断。方法回顾1例LMNA基因突变引起的肌营养不良症病例的临床资料,并复习相关文献。结果患儿,女,8个月,临床表现为抬头乏力、眼睑下垂、运动发育迟缓。检测患儿及其父母、姐姐的LMNA...目的探讨LMNA相关的先天性肌营养不良症的临床特征和诊断。方法回顾1例LMNA基因突变引起的肌营养不良症病例的临床资料,并复习相关文献。结果患儿,女,8个月,临床表现为抬头乏力、眼睑下垂、运动发育迟缓。检测患儿及其父母、姐姐的LMNA基因,显示患儿存在杂合突变c.94-96 del AAG(p.K32del),确诊为LMNA突变引起的肌营养不良。患儿父母及姐姐均未发现LMNA基因突变。文献检索显示,LMNA相关的先天性肌营养不良症患儿80%以上以抬头乏力为主要表现,并且可能交叉重叠存在肢体近端肌无力、运动发育迟缓、轴向肌无力。结论 LMNA基因分析有助于早期诊断先天性肌营养不良。展开更多
