The muscular dystrophy causes in women with DMD-diagnosis

Abstract

The results of a study of 38 female with a clinical diagnosis of «Duchenne/Becker muscular dystrophy». All probands searched for deletions / duplications DMD gene, number of sex chromosomes and X inactivation, mutations in autosomal recessive LGMD-genes: CAPN3, FKRP, SGCA, SGCB, SGCG, SGCD. The cause of muscular dystrophy was established in 45% of the examined probands. It is shown that it is impossible to confirm the diagnosis of muscular dystrophy in women on the basis of detection of unbalanced X-chromosome inactivation. The medical technology «Single tube detection system for frequency sarcoglicans mutations» was introduced into the practical activity of the Research Centre for Medical Genetics.
