Genes affected
ARNT2 (HGNC:16876): (aryl hydrocarbon receptor nuclear translocator 2) This gene encodes a member of the basic-helix-loop-helix-Per-Arnt-Sim (bHLH-PAS) superfamily of transcription factors. The encoded protein acts as a partner for several sensor proteins of the bHLH-PAS family, forming heterodimers with the sensor proteins that bind regulatory DNA sequences in genes responsive to developmental and environmental stimuli. Under hypoxic conditions, the encoded protein complexes with hypoxia-inducible factor 1alpha in the nucleus and this complex binds to hypoxia-responsive elements in enhancers and promoters of oxygen-responsive genes. A highly similar protein in mouse forms functional complexes with both aryl hydrocarbon receptors and Single-minded proteins, suggesting additional roles for the encoded protein in the metabolism of xenobiotic compounds and the regulation of neurogenesis, respectively.

Submissions by phenotype

Uncertain significance, criteria provided, single submitterclinical testingInvitaeJul 20, 2022In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant has not been reported in the literature in individuals affected with ARNT2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change affects codon 37 of the ARNT2 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the ARNT2 protein. -
