摘要
目的 :探讨常染色体隐性遗传的类杜氏肌营养不良 (类 DMD)临床特点及其在杜氏肌营养不良症(DMD)中的比例。方法 :研究 8个家系中 9例女性类 DMD的临床表现、家族史及血清肌酸激酶水平 ,并估计常染色体隐性遗传的类 DMD在 DMD中的比例。结果 :常染色体隐性遗传的类 DMD患者独立行走的平均时间为 (1.47± 1.0 0 )岁 ,症状出现的平均时间为 (8.11± 4.32 )岁 ,血清肌酸激酶平均水平为 (2 785 .10± 15 0 0 .2 9) U/ L,这种常染色体隐性遗传型类 DMD占 DMD的 9.4%。结论 :常染色体隐性遗传的类 DMD与 DMD在临床上无法区别 ,部分被认为是性连锁隐性遗传的 DMD,实际上是常染色体隐性遗传的类
Objective:Our aim was to investigate the proportion of autosomal recessive (AR) inheritance among families with patients with Duchenne muscular dystrophy (DMD) and clinical feature in patients with AR form of DMD. Methods:A total of 193 families was studied, 8 of them with at least one girl with “DMD - like” phenotype and 185 with only boys with this kind of phenotype. Based on the number of families with at least one affected girl and the number of patients per sibship among these pedigrees, the proportion of families with DMD inherited as an AR trait was estimated. The clinical examination, family history and serum creatine kinase were studied in 11 patients diagnosed as AR form of DMD. Results: The proportion of families with AR form of DMD was estimated as 9.4%. The average age of being able to walk is (1.47±1.00) year, serum creatine kinase levels were (2785.10±1500.29) U/L. The clinical symptom occurred at the average age of (8.11±4.32) year in patients with AR form of DMD. Conclusion: The AR form of muscular dystrophy and DMD not be distingushed clinically. Some families with only affected boys diagnosed as typical DMD, in fact, have the AR form of the disease. This study is very useful for genetic consulting.
