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]

Ambry Genetics

Jul 15, 2021

The c.1744T>C (p.F582L) alteration is located in exon 18 (coding exon 17) of the CAPN14 gene. This alteration results from a T to C substitution at nucleotide position 1744, causing the phenylalanine (F) at amino acid position 582 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
