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]

The c.813C>A (p.D271E) alteration is located in exon 11 (coding exon 10) of the ERMAP gene. This alteration results from a C to A substitution at nucleotide position 813, causing the aspartic acid (D) at amino acid position 271 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
