Genes affected

ONECUT2 (HGNC:8139): (one cut homeobox 2) This gene encodes a member of the onecut family of transcription factors, which are characterized by a cut domain and an atypical homeodomain. The protein binds to specific DNA sequences and stimulates expression of target genes, including genes involved in melanocyte and hepatocyte differentiation. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.31).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.468 is higher than 0.05.
