Genes affected

CRTAM (HGNC:24313): (cytotoxic and regulatory T cell molecule) The CRTAM gene is upregulated in CD4 (see MIM 186940)-positive and CD8 (see CD8A; MIM 186910)-positive T cells and encodes a type I transmembrane protein with V and C1-like Ig domains (Yeh et al., 2008 [PubMed 18329370]).[supplied by OMIM, Feb 2009]

ENSG00000285909 (HGNC:):
