Genes affected

RGMA (HGNC:30308): (repulsive guidance molecule BMP co-receptor a) This gene encodes a member of the repulsive guidance molecule family. The encoded protein is a glycosylphosphatidylinositol-anchored glycoprotein that functions as an axon guidance protein in the developing and adult central nervous system. This protein may also function as a tumor suppressor in some cancers. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.93).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.8 is higher than 0.05.
