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]

The c.578C>T (p.T193M) alteration is located in exon 5 (coding exon 5) of the CRTAM gene. This alteration results from a C to T substitution at nucleotide position 578, causing the threonine (T) at amino acid position 193 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
