Variant summary

Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_Strong BP6_Very_Strong BA1

The ENST00000242057.9(AHR):​c.1661G>A​(p.Arg554Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.134 in 1,613,866 control chromosomes in the GnomAD database, including 20,829 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt. Synonymous variant affecting the same amino acid position (i.e. R554R) has been classified as Likely benign.

Genes affected

AHR (HGNC:348): (aryl hydrocarbon receptor) The protein encoded by this gene is a ligand-activated helix-loop-helix transcription factor involved in the regulation of biological responses to planar aromatic hydrocarbons. This receptor has been shown to regulate xenobiotic-metabolizing enzymes such as cytochrome P450. Before ligand binding, the encoded protein is sequestered in the cytoplasm; upon ligand binding, this protein moves to the nucleus and stimulates transcription of target genes.

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0014748573).
• BP6: Variant 7-17339486-G-A is Benign according to our data. Variant chr7-17339486-G-A is described in ClinVar as [Benign]. Clinvar id is 1168239.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.447 is higher than 0.05.
