Genes affected

NR5A2 (HGNC:7984): (nuclear receptor subfamily 5 group A member 2) The protein encoded by this gene is a DNA-binding zinc finger transcription factor and is a member of the fushi tarazu factor-1 subfamily of orphan nuclear receptors. The encoded protein is involved in the expression of genes for hepatitis B virus and cholesterol biosynthesis, and may be an important regulator of embryonic development.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.08).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.534 is higher than 0.05.
