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 GeneticsApr 25, 2023The c.1340C>G (p.P447R) alteration is located in exon 11 (coding exon 10) of the ERMAP gene. This alteration results from a C to G substitution at nucleotide position 1340, causing the proline (P) at amino acid position 447 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
