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]

The c.130C>G (p.Q44E) alteration is located in exon 2 (coding exon 1) of the BMP2 gene. This alteration results from a C to G substitution at nucleotide position 130, causing the glutamine (Q) at amino acid position 44 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
