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.

The c.691C>G (p.H231D) alteration is located in exon 6 (coding exon 6) of the CALR3 gene. This alteration results from a C to G substitution at nucleotide position 691, causing the histidine (H) at amino acid position 231 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

In summary, this variant has uncertain impact on CALR3 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with a CALR3-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with aspartic acid at codon 231 of the CALR3 protein (p.His231Asp). The histidine residue is moderately conserved and there is a moderate physicochemical difference between histidine and aspartic acid. -
