Genes affected

MMD (HGNC:7153): (monocyte to macrophage differentiation associated) This protein is expressed by in vitro differentiated macrophages but not freshly isolated monocytes. Although sequence analysis identifies seven potential transmembrane domains, this protein has little homology to G-protein receptors and it has not been positively identified as a receptor. A suggested alternative function is that of an ion channel protein in maturing macrophages. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.75).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.414 is higher than 0.05.
