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]

Submissions by phenotype
not specified Uncertain:1
| Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 21, 2024 | The c.504G>T (p.W168C) alteration is located in exon 2 (coding exon 2) of the BMP3 gene. This alteration results from a G to T substitution at nucleotide position 504, causing the tryptophan (W) at amino acid position 168 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
