Genes affected

PTH1R (HGNC:9608): (parathyroid hormone 1 receptor) The protein encoded by this gene is a member of the G-protein coupled receptor family 2. This protein is a receptor for parathyroid hormone (PTH) and for parathyroid hormone-like hormone (PTHLH). The activity of this receptor is mediated by G proteins which activate adenylyl cyclase and also a phosphatidylinositol-calcium second messenger system. Defects in this receptor are known to be the cause of Jansen's metaphyseal chondrodysplasia (JMC), chondrodysplasia Blomstrand type (BOCD), as well as enchodromatosis. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, May 2010]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.08208701).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000131 (2/152326) while in subpopulation EAS AF= 0.000387 (2/5174). AF 95% confidence interval is 0.0000684. There are 0 homozygotes in gnomad4. There are 1 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.34C>T (p.L12F) alteration is located in exon 3 (coding exon 1) of the PTH1R gene. This alteration results from a C to T substitution at nucleotide position 34, causing the leucine (L) at amino acid position 12 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
