Genes affected

NEIL3 (HGNC:24573): (nei like DNA glycosylase 3) NEIL3 belongs to a class of DNA glycosylases homologous to the bacterial Fpg/Nei family. These glycosylases initiate the first step in base excision repair by cleaving bases damaged by reactive oxygen species and introducing a DNA strand break via the associated lyase reaction (Bandaru et al., 2002 [PubMed 12509226]).[supplied by OMIM, Mar 2008]

(HGNC:):

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.3).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.316 is higher than 0.05.
