Genes affected

BMP5 (HGNC:1072): (bone morphogenetic protein 5) 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. Polymorphisms in this gene may be associated with osteoarthritis in human patients. This gene is differentially regulated in multiple human cancers. This gene encodes distinct protein isoforms that may be similarly proteolytically processed. [provided by RefSeq, Jul 2016]

Ambry Genetics

Nov 03, 2022

The c.1203A>G (p.I401M) alteration is located in exon 6 (coding exon 6) of the BMP5 gene. This alteration results from a A to G substitution at nucleotide position 1203, causing the isoleucine (I) at amino acid position 401 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
