Comment on list classification: Updated rating from Grey to Red. Gene was added to the panel and rated Green by external expert Michael Coleman (11 Sept 2019). Currently insufficient evidence for a Green rating: one case (2 siblings) with pain disorder in PMID:31132363, and a mouse model. Not currently associated with a phenotype in OMIM or Gene2Phenotype. Therefore rated Red awaiting further evidence.

PMID:31132363, Huppke et al., 2019 report a homozygous missense variant (c.281C>T (T94M) in NMNAT2 in 2 siblings with childhood-onset polyneuropathy with erythromelalgia. Erythromelalgia is a rare clinical syndrome characterized by intermittent attacks of intense burning pain with redness and swelling.
