Genes affected

CALCR (HGNC:1440): (calcitonin receptor) This gene encodes a high affinity receptor for the peptide hormone calcitonin and belongs to a subfamily of seven transmembrane-spanning G protein-coupled receptors. The encoded protein is involved in maintaining calcium homeostasis and in regulating osteoclast-mediated bone resorption. Polymorphisms in this gene have been associated with variations in bone mineral density and onset of osteoporosis. Alternate splicing results in multiple transcript variants.

Variant summary: CALCR c.1358delA (p.Asn453ThrfsX13) results in a premature termination codon, predicted to cause a truncation of the encoded protein. However, clinical and functional evidence currently available does not allow for definitive conclusions on whether loss-of-function variants in the CALCR gene cause disease. The variant allele was found at a frequency of 0.00021 in 251494 control chromosomes (52/251494 chromosomes from the gnomAD database). To our knowledge, no occurrence of c.1358delA in individuals affected with Postmenopausal Osteoporosis and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. -
