Genes affected
CALR3 (HGNC:20407): (calreticulin 3) The protein encoded by this gene belongs to the calreticulin family, members of which are calcium-binding chaperones localized mainly in the endoplasmic reticulum. This protein is also localized to the endoplasmic reticulum lumen, however, its capacity for calcium-binding may be absent or much lower than other family members. This gene is specifically expressed in the testis, and may be required for sperm fertility. Mutation in this gene has been associated with familial hypertrophic cardiomyopathy.

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 357 of the CALR3 protein (p.Glu357Lys). This variant is present in population databases (rs777429499, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with CALR3-related conditions. ClinVar contains an entry for this variant (Variation ID: 410621). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CALR3 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. -

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

The c.1069G>A (p.E357K) alteration is located in exon 9 (coding exon 9) of the CALR3 gene. This alteration results from a G to A substitution at nucleotide position 1069, causing the glutamic acid (E) at amino acid position 357 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
