Genes affected
CAPN1 (HGNC:1476): (calpain 1) 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 the large subunit of the ubiquitous enzyme, calpain 1. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Nov 2010]

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Nov 05, 2016 | The p.Met640Arg variant in CAPN1 has not been previously reported in the literat ure and was absent from large population studies. Computational prediction tools and conservation analysis suggest that the variant may impact the protein, thou gh this information is not predictive enough to determine pathogenicity. In summ ary, the clinical significance of the p.Met640Arg variant is uncertain. - |
