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

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM1
In a propeptide (size 248) in uniprot entity BMP15_HUMAN there are 8 pathogenic changes around while only 0 benign (100%) in NM_005448.2
BP4
Computational evidence support a benign effect (MetaRNN=0.17993116).
BS2
High Hemizygotes in GnomAdExome4 at 6 XL geneVariant has number of hemizygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.590A>T (p.N197I) alteration is located in exon 2 (coding exon 2) of the BMP15 gene. This alteration results from a A to T substitution at nucleotide position 590, causing the asparagine (N) at amino acid position 197 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
