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]

May 21, 2024

The c.1001A>C (p.D334A) alteration is located in exon 4 (coding exon 4) of the RGMA gene. This alteration results from a A to C substitution at nucleotide position 1001, causing the aspartic acid (D) at amino acid position 334 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
