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]

Ambry Genetics

Feb 10, 2022

The c.5590G>A (p.V1864I) alteration is located in exon 39 (coding exon 39) of the ATG2B gene. This alteration results from a G to A substitution at nucleotide position 5590, causing the valine (V) at amino acid position 1864 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
