Comment on mode of inheritance: Changed from 'other' to monoallelic, due to reports of heterozygous variants to enable variants in this gene to be tiered.

Rebecca Foulger (Genomics England curator)

Green List (high evidence)

>3 cases including PMID:20847235 who detected heterozygous germline variants in IDH2 that alter Arg140 in 15 unrelated patients with MIM:613657; in 14 cases the variant was de novo. The mother of 1 patient demonstrated germline mosaicism. PMID:24049096 also report a heterozygous IDH2 and the unaffected mother was a mosaic carrier. Somatic variants also reported.
