Comment on list classification: Axonal degenerative polyneuropathy and demyelinating sensorimotor polyneuropathy are observed in the more severely affected individuals with biallelic variants in this gene. There are sufficient cases with a relevant phenotype (5 individuals from 3 families) to rate as Green at the next GMS panel update.
