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.

Hypertrophic cardiomyopathy 19 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJan 17, 2023In 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. ClinVar contains an entry for this variant (Variation ID: 573600). This variant has not been reported in the literature in individuals affected with CALR3-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change results in a frameshift in the CALR3 gene (p.Gln377Phefs*14). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 8 amino acid(s) of the CALR3 protein and extend the protein by 5 additional amino acid residues. -
