Genes affected

CAPN13 (HGNC:16663): (calpain 13) The calpains, calcium-activated neutral proteases, are nonlysosomal, intracellular cysteine proteases. The mammalian calpains include ubiquitous, stomach-specific, and muscle-specific proteins. The ubiquitous enzymes consist of heterodimers with distinct large, catalytic subunits associated with a common small, regulatory subunit. This gene encodes a member of the calpain large subunit family. [provided by RefSeq, Jun 2012]

The c.1967A>C (p.Y656S) alteration is located in exon 21 (coding exon 20) of the CAPN13 gene. This alteration results from a A to C substitution at nucleotide position 1967, causing the tyrosine (Y) at amino acid position 656 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
