Genes affected

BMP3 (HGNC:1070): (bone morphogenetic protein 3) 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. This protein suppresses osteoblast differentiation, and negatively regulates bone density, by modulating TGF-beta receptor availability to other ligands. [provided by RefSeq, Jul 2016]

Sep 29, 2023

The c.198G>C (p.R66S) alteration is located in exon 1 (coding exon 1) of the BMP3 gene. This alteration results from a G to C substitution at nucleotide position 198, causing the arginine (R) at amino acid position 66 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
