Novel Homozygous Missense Mutation in CAPN3 Gene Detected in a Saudi Arabian Family With Limb–Girdle Muscular Dystrophy Type 2A

We report a Saudi Arabian family with weakness in limb–girdle distribution: waddling gait, positive Gowers' sign, and marked muscle atrophy in the shoulder and pelvic girdle muscles. We sequenced all exonic and intronic regions of the CAPN3 gene and identified c.1699 G>A variant as a novel variant not previously described in other patients. In silico predictions indicate that this is probably a disease-causing mutation. Here, for the first time, we report this c.1699 G>A new variant in the CAPN3 gene that can be considered as a robust genetics factor causing LGMD2A disease.
