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.

CALR3 NM_145046.4 exon 7 p.Thr283Ile (c.848C>T): This variant has not been reported in the literature but is present in 0.5% (126/24970) of African alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/19-16593331-G-A). This variant is present in ClinVar (Variation ID:416239). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
