Polymorphismi

ERMAP is responsible for the Scianna/Radin blood group system which comprises seven different antigens. The Sc1 and Sc2 antigens are resulting from a single variation in position 57; Arg-57 corresponds to the Sc2 antigen and Gly-57 to the Sc1 antigen. The Sc2 antigen is rare with an occurrence of less than 1% in the population while Sc1 is more frequent. Sc3 is not expressed by individuals homozygous for a null allele encoding a truncated protein lacking its extracellular part (Sc-3). The Sc4 antigen corresponding to the previously defined Radin blood group antigen (Rd) is due to a single variation in position 60; Ala-60 corresponds to Sc4/Rd+, the antigenic form of the protein. Sc4 is found in less than 1% of the population. Sc5/STAR, Sc6/SCER and Sc7/SCAN antigens are due to single variations in positions 47, 81 and 35 respectively. Alloantibodies to the low frequency Sc2 and Sc4 antigens are the cause of hemolytic disease in the newborn.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
