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.261C>G (p.D87E) alteration is located in exon 1 (coding exon 1) of the BMP8A gene. This alteration results from a C to G substitution at nucleotide position 261, causing the aspartic acid (D) at amino acid position 87 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
