Genes affected

CAPN14 (HGNC:16664): (calpain 14) Calpains are a family of cytosolic calcium-activated cysteine proteases involved in a variety of cellular processes including apoptosis, cell division, modulation of integrin-cytoskeletal interactions, and synaptic plasticity (Dear et al., 2000 [PubMed 10964513]). CAPN14 belongs to the calpain large subunit family.[supplied by OMIM, Mar 2008]

The c.1966A>G (p.M656V) alteration is located in exon 20 (coding exon 19) of the CAPN14 gene. This alteration results from a A to G substitution at nucleotide position 1966, causing the methionine (M) at amino acid position 656 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
