Genes affected
ERMAP (HGNC:15743): (erythroblast membrane associated protein (Scianna blood group)) The protein encoded by this gene is a cell surface transmembrane protein that may act as an erythroid cell receptor, possibly as a mediator of cell adhesion. Polymorphisms in this gene are responsible for the Scianna/Radin blood group system. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 16, 2023The c.320G>A (p.G107E) alteration is located in exon 3 (coding exon 2) of the ERMAP gene. This alteration results from a G to A substitution at nucleotide position 320, causing the glycine (G) at amino acid position 107 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
