Genes affected

ARNT (HGNC:700): (aryl hydrocarbon receptor nuclear translocator) This gene encodes a protein containing a basic helix-loop-helix domain and two characteristic PAS domains along with a PAC domain. The encoded protein binds to ligand-bound aryl hydrocarbon receptor and aids in the movement of this complex to the nucleus, where it promotes the expression of genes involved in xenobiotic metabolism. This protein is also a co-factor for transcriptional regulation by hypoxia-inducible factor 1. Chromosomal translocation of this locus with the ETV6 (ets variant 6) gene on chromosome 12 have been described in leukemias. Alternative splicing results in multiple transcript variants.

The c.127C>T (p.R43W) alteration is located in exon 2 (coding exon 2) of the ARNT gene. This alteration results from a C to T substitution at nucleotide position 127, causing the arginine (R) at amino acid position 43 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
