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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.517C>G (p.L173V) alteration is located in exon 3 (coding exon 3) of the RGMA gene. This alteration results from a C to G substitution at nucleotide position 517, causing the leucine (L) at amino acid position 173 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
