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]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.12395775).
• BS2: High AC in GnomAdExome4 at 50 AD gene.

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 22 of the CAPN5 protein (p.Arg22His). This variant is present in population databases (rs782464684, gnomAD 0.02%). 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: 1040199). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt CAPN5 protein function with a negative predictive value of 80%. 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. -
