Abstract:
We reported an age 32 male with progressive proximal muscle weakness. The serum creatine kinase was 1,908 IU/L. The muscle biopsy from biceps brachii muscle showed nonspecific myopathic changes. The whole exome sequencing identified a heterozygous variant (c.296A>C) in CAV3. It was previously reported as a likely pathogenic variant. It was also detected in the male’s mother and brother. However, his mother and brother had only hyperCKemia without muscle weakness. Our case showed phenotypic heterogeneity in a family, with the same variant in CAV3.
