Genes affected

BMPR1B (HGNC:1077): (bone morphogenetic protein receptor type 1B) This gene encodes a member of the bone morphogenetic protein (BMP) receptor family of transmembrane serine/threonine kinases. The ligands of this receptor are BMPs, which are members of the TGF-beta superfamily. BMPs are involved in endochondral bone formation and embryogenesis. These proteins transduce their signals through the formation of heteromeric complexes of 2 different types of serine (threonine) kinase receptors: type I receptors of about 50-55 kD and type II receptors of about 70-80 kD. Type II receptors bind ligands in the absence of type I receptors, but they require their respective type I receptors for signaling, whereas type I receptors require their respective type II receptors for ligand binding. Mutations in this gene have been associated with primary pulmonary hypertension. Several transcript variants encoding two different isoforms have been found for this gene.

The BMPR1B c.11G>A variant is predicted to result in the amino acid substitution p.Arg4Gln. This variant has been reported as uncertain in an individual with primary ovarian insufficiency (reported as p.Arg34Gln in Table S7, Heddar. et al 2022. PubMed ID: 36099812). This variant is reported in 0.062% of alleles in individuals of European (Non-Finnish) descent in gnomAD. In ClinVar, this variant has been reported as benign/likely benign/uncertain (https://preview.ncbi.nlm.nih.gov/clinvar/variation/906582/). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
