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.

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The BMPR1B c.1112G>A variant is predicted to result in the amino acid substitution p.Arg371Gln. This variant was reported in an individual with pulmonary arterial hypertension (Supplementary Dataset 1 in Wang et al. 2018. PubMed ID: 30578397) and in a patient with cleft lip with/without cleft palate (Marini et al. 2019. PubMed ID: 31063268). This variant is reported in 0.13% of alleles in individuals of South Asian descent in gnomAD, including one homozygous individual. This variant has been interpreted by a single submitter in ClinVar as likely benign (https://preview.ncbi.nlm.nih.gov/clinvar/variation/441001/). 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. -
