Genes affected

TBX21 (HGNC:11599): (T-box transcription factor 21) This gene is a member of a phylogenetically conserved family of genes that share a common DNA-binding domain, the T-box. T-box genes encode transcription factors involved in the regulation of developmental processes. This gene is the human ortholog of mouse Tbx21/Tbet gene. Studies in mouse show that Tbx21 protein is a Th1 cell-specific transcription factor that controls the expression of the hallmark Th1 cytokine, interferon-gamma (IFNG). Expression of the human ortholog also correlates with IFNG expression in Th1 and natural killer cells, suggesting a role for this gene in initiating Th1 lineage development from naive Th precursor cells.

Ambry Genetics

Sep 26, 2023

The c.112C>T (p.P38S) alteration is located in exon 1 (coding exon 1) of the TBX21 gene. This alteration results from a C to T substitution at nucleotide position 112, causing the proline (P) at amino acid position 38 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
