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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2023The c.211C>G (p.L71V) alteration is located in exon 3 (coding exon 2) of the RGMB gene. This alteration results from a C to G substitution at nucleotide position 211, causing the leucine (L) at amino acid position 71 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
