Monogenic diabetes
Gene: HNF1AComment on mode of inheritance: Homozygous loss-of-function germline variants are thought to be embryonically lethal, however one family including three insulin-treated family members diagnosed with diabetes before 20 years of age was identified by Misra et al. 2020 (PMID: 32001615) with a homozygous hypomorphic variant in the HNF1A gene. This is not yet sufficient to update the MOI but should be noted if further recessive cases are reported in the future.Created: 3 Nov 2022, 3:04 p.m. | Last Modified: 3 Nov 2022, 3:04 p.m.
