Genes affected
GREM2 (HGNC:17655): (gremlin 2, DAN family BMP antagonist) This gene encodes a member of the BMP (bone morphogenic protein) antagonist family. Like BMPs, BMP antagonists contain cystine knots and typically form homo- and heterodimers. The CAN (cerberus and dan) subfamily of BMP antagonists, to which this gene belongs, is characterized by a C-terminal cystine knot with an eight-membered ring. The antagonistic effect of the secreted glycosylated protein encoded by this gene is likely due to its direct binding to BMP proteins. As an antagonist of BMP, this gene may play a role in regulating organogenesis, body patterning, and tissue differentiation. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 2 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 1.2306 (below the threshold of 3.09). Trascript score misZ: 0.5294 (below the threshold of 3.09).
BP4
Computational evidence support a benign effect (MetaRNN=0.073221475).
BS2
High AC in GnomAd4 at 16 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
