Variants for SMIM1 Gene

Polymorphic Variants from UniProtKB/Swiss-Prot for SMIM1 Gene

SMIM1 is responsible for the Vel blood group system (VEL) [MIM:615264]. The Vel antigen is present on red blood cells from all people except rare Vel-negative individuals who can form antibodies to Vel in response to transfusion or pregnancy. These antibodies may cause severe hemolytic reactions in blood recipients. In most cases, Vel-negative individuals are homozygous for a 17 nucleotide frameshift deletion in exon 3. In some cases, Vel-negative are heterozygous for the 17 nucleotide frameshift deletion and a missense variant at position 51.
