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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.775G>A (p.E259K) alteration is located in exon 7 (coding exon 7) of the CRTAM gene. This alteration results from a G to A substitution at nucleotide position 775, causing the glutamic acid (E) at amino acid position 259 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
