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.

Variant summary: The CALR3 c.850G>A (p.Asp284Asn) variant involves the alteration of a non-conserved nucleotide. 4/4 in silico tools predict benign outcome for this variant (SNPsandGO not captured due to low reliability index). This variant was found in 204/121410 control chromosomes (4 homozygotes) from ExAC, predominantly observed in the African subpopulation at a frequency of 0.017782 (185/10404). This frequency is about 711 times the estimated maximal expected allele frequency of a pathogenic CALR3 variant (0.000025), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. In addition, multiple clinical diagnostic laboratories/reputable databases in ClinVar have classified this variant as benign. To our knowledge, this variant has not been reported in affected individuals in literature. Taken together, this variant is classified as benign. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
