Summaries for SMIM1 Gene

Entrez Gene Summary for SMIM1 Gene

  • This gene encodes a small, conserved protein that participates in red blood cell formation. The encoded protein is localized to the cell membrane and is the antigen for the Vel blood group. Alternative splicing results in different transcript variants that encode the same protein. [provided by RefSeq, Dec 2013]

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
