Genes affected
THEMIS (HGNC:21569): (thymocyte selection associated) This gene encodes a protein that plays a regulatory role in both positive and negative T-cell selection during late thymocyte development. The protein functions through T-cell antigen receptor signaling, and is necessary for proper lineage commitment and maturation of T-cells. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.1733C>T (p.T578M) alteration is located in exon 4 (coding exon 4) of the THEMIS gene. This alteration results from a C to T substitution at nucleotide position 1733, causing the threonine (T) at amino acid position 578 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
