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.1519G>A (p.V507I) alteration is located in exon 14 (coding exon 13) of the CAPN14 gene. This alteration results from a G to A substitution at nucleotide position 1519, causing the valine (V) at amino acid position 507 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
