Hereditary Neuropathy - complex
Gene: OPA3
Peripheral neuropathy has been reported in multiple individuals with ADOA associated with OPA3. Haploinsufficiency is not expected to be the mechanism of disease. Gain of function or dominant negative effect have been suggested mechanisms of disease.
PMID: 31119193 - 9 of the 12 affected individuals from 3 families with OPA3 missense (p.Met8Thr, & p.Gln105Glu) had a possible or confirmed peripheral neuropathy. Was presenting feature in a single case.
PMID: 28050599 - de novo c.235C>G p.(Leu79Val) identified in a woman who presented with cataracts, optic atrophy, lipodystrophy/lipoatrophy, and peripheral neuropathy.
