Genes affected
CAPN5 (HGNC:1482): (calpain 5) Calpains are calcium-dependent cysteine proteases involved in signal transduction in a variety of cellular processes. A functional calpain protein consists of an invariant small subunit and 1 of a family of large subunits. CAPN5 is one of the large subunits. Unlike some of the calpains, CAPN5 and CAPN6 lack a calmodulin-like domain IV. Because of the significant similarity to Caenorhabditis elegans sex determination gene tra-3, CAPN5 is also called as HTRA3. [provided by RefSeq, Jul 2008]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.23A>G (p.Y8C) alteration is located in exon 2 (coding exon 1) of the CAPN5 gene. This alteration results from a A to G substitution at nucleotide position 23, causing the tyrosine (Y) at amino acid position 8 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 8 of the CAPN5 protein (p.Tyr8Cys). This variant is present in population databases (no rsID available, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with CAPN5-related conditions. ClinVar contains an entry for this variant (Variation ID: 1013862). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
