Genes affected

ATG2B (HGNC:20187): (autophagy related 2B) This gene encodes a protein required for autophagy. The encoded protein is involved in autophagosome formation. A germline duplication of a region that includes this gene is associated with predisposition to myeloid malignancies. [provided by RefSeq, Jul 2016]

ACMG classification

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

• BP4: Computational evidence support a benign effect (MetaRNN=0.002118796).
• BP6: Variant 14-96302043-T-G is Benign according to our data. Variant chr14-96302043-T-G is described in ClinVar as Benign. ClinVar VariationId is 1281030.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.0879 is higher than 0.05.
