Genes affected

CASR (HGNC:1514): (calcium sensing receptor) The protein encoded by this gene is a plasma membrane G protein-coupled receptor that senses small changes in circulating calcium concentration. The encoded protein couples this information to intracellular signaling pathways that modify parathyroid hormone secretion or renal cation handling, and thus this protein plays an essential role in maintaining mineral ion homeostasis. Mutations in this gene are a cause of familial hypocalciuric hypercalcemia, neonatal severe hyperparathyroidism, and autosomal dominant hypocalcemia. [provided by RefSeq, Aug 2017]

Computational evidence support a benign effect (BayesDel_noAF=-0.39).

BP6

Variant 3-122261920-C-T is Benign according to our data. Variant chr3-122261920-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 281446.

BP7

Synonymous conserved (PhyloP=1.08 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000263 (40/152320) while in subpopulation AFR AF = 0.00089 (37/41574). AF 95% confidence interval is 0.000664. There are 0 homozygotes in GnomAd4. There are 17 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
