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]

Sep 12, 2023

The c.730C>A (p.P244T) alteration is located in exon 4 (coding exon 3) of the RGMB gene. This alteration results from a C to A substitution at nucleotide position 730, causing the proline (P) at amino acid position 244 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
