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.1706G>A (p.R569H) alteration is located in exon 18 (coding exon 17) of the CAPN13 gene. This alteration results from a G to A substitution at nucleotide position 1706, causing the arginine (R) at amino acid position 569 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
