Genes affected

BMP8A (HGNC:21650): (bone morphogenetic protein 8a) 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 may play a role in development of the reproductive system. This gene may have arose from a gene duplication event and its gene duplicate is also present on chromosome 1. [provided by RefSeq, Jul 2016]

The c.325G>A (p.V109I) alteration is located in exon 1 (coding exon 1) of the BMP8A gene. This alteration results from a G to A substitution at nucleotide position 325, causing the valine (V) at amino acid position 109 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
