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.

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0241 (3536/146944) while in subpopulation AMR AF= 0.053 (787/14836). AF 95% confidence interval is 0.05. There are 70 homozygotes in gnomad4. There are 1772 alleles in male gnomad4 subpopulation. Median coverage is 22. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 70 AR gene
