Genes affected

BMP2 (HGNC:1069): (bone morphogenetic protein 2) This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer, which plays a role in bone and cartilage development. Duplication of a regulatory region downstream of this gene causes a form of brachydactyly characterized by a malformed index finger and second toe in human patients. [provided by RefSeq, Jul 2016]

This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 45 of the BMP2 protein (p.Pro45Thr). This variant is present in population databases (rs757825179, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with BMP2-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
