Genes affected

GDF9 (HGNC:4224): (growth differentiation factor 9) 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 regulates ovarian function. Reduced expression of this gene may be associated with polycystic ovary syndrome and mutations in this gene may be more common in mothers of dizygotic twins. [provided by RefSeq, Jul 2016]

The c.1232A>G (p.D411G) alteration is located in exon 2 (coding exon 2) of the GDF9 gene. This alteration results from a A to G substitution at nucleotide position 1232, causing the aspartic acid (D) at amino acid position 411 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
