Objective:
To investigate the clinical features and CLCN1 gene mutation in three families with Myotonia Congenita.
Methods:
Clinical data collected from 8 patients in three Myotonia Congenital families were summarized. Genomic DNAs were extracted from peripheral blood of family members and 100 normal controls. The coding regions of CLCN1 were analyzed according to polymerase chain reaction (PCR) and DNA sequencing.
Results:
All patients from three Myotonia Congenita families showed ...
