Genes affected

RGMB (HGNC:26896): (repulsive guidance molecule BMP co-receptor b) RGMB is a glycosylphosphatidylinositol (GPI)-anchored member of the repulsive guidance molecule family (see RGMA, MIM 607362) and contributes to the patterning of the developing nervous system (Samad et al., 2005 [PubMed 15671031]).[supplied by OMIM, Apr 2009]

Ambry Genetics

Mar 27, 2023

The c.203C>T (p.P68L) alteration is located in exon 3 (coding exon 2) of the RGMB gene. This alteration results from a C to T substitution at nucleotide position 203, causing the proline (P) at amino acid position 68 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
