Genes affected

ATG16L1 (HGNC:21498): (autophagy related 16 like 1) The protein encoded by this gene is part of a large protein complex that is necessary for autophagy, the major process by which intracellular components are targeted to lysosomes for degradation. Defects in this gene are a cause of susceptibility to inflammatory bowel disease type 10 (IBD10). Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jun 2010]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.06).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.764 is higher than 0.05.
