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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 30, 2023The c.5984A>G (p.K1995R) alteration is located in exon 41 (coding exon 41) of the ATG2B gene. This alteration results from a A to G substitution at nucleotide position 5984, causing the lysine (K) at amino acid position 1995 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
