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

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=1.8645105E-5).
• BP6: Variant 2-233274722-A-G is Benign according to our data. Variant chr2-233274722-A-G is described in ClinVar as Benign. ClinVar VariationId is 1130.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.515 is higher than 0.05.
