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.1903G>A (p.G635S) alteration is located in exon 20 (coding exon 19) of the CAPN14 gene. This alteration results from a G to A substitution at nucleotide position 1903, causing the glycine (G) at amino acid position 635 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
