Genes affected

AHRR (HGNC:346): (aryl hydrocarbon receptor repressor) The protein encoded by this gene participates in the aryl hydrocarbon receptor (AhR) signaling cascade, which mediates dioxin toxicity, and is involved in regulation of cell growth and differentiation. It functions as a feedback modulator by repressing AhR-dependent gene expression. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

The c.638C>T (p.T213M) alteration is located in exon 7 (coding exon 7) of the AHRR gene. This alteration results from a C to T substitution at nucleotide position 638, causing the threonine (T) at amino acid position 213 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
