Genes affected

BMP15 (HGNC:1068): (bone morphogenetic protein 15) 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 subunits of a disulfide-linked homodimer, or alternatively, a heterodimer, with the related protein, growth differentiation factor 9 (GDF9). This protein plays a role in oocyte maturation and follicular development, through activation of granulosa cells. Defects in this gene are the cause of ovarian dysgenesis and are associated with premature ovarian failure. [provided by RefSeq, Aug 2016]

ACMG classification

Identified in patients with premature ovarian insufficiency referred for genetic testing at GeneDx and in published literature (Di Pasquale et al., 2006); Identified in a patient with polycystic ovary syndrome and normal serum androgen levels in published literature (Crespo et al., 2022); Published functional studies demonstrate a reduction of mature protein production and decreased synergy with GDF9, however, the biological significance of these effects is uncertain (Rossetti et al., 2009; Patio et al., 2017); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 34426522, 35898701, 28359091, 19377476, 16464940, 19263482) -
