Peroxisome Biogenesis Disorder 7b; Pbd7b

Description

The overlapping phenotypes of neonatal adrenoleukodystrophy (NALD) and infantile Refsum disease (IRD) represent the milder manifestations of the Zellweger syndrome spectrum (ZSS) of peroxisome biogenesis disorders. The clinical course of patients with the NALD and IRD presentation is variable and may include developmental delay, hypotonia, liver dysfunction, sensorineural hearing loss, retinal dystrophy, and visual impairment. Children with the NALD presentation may reach their teens, and those with the IRD presentation may reach adulthood (summary by Waterham and Ebberink, 2012).For a complete phenotypic description and a discussion of genetic heterogeneity of PBD(NALD/IRD), see {601539}.Individuals with mutations in the PEX26 gene have cells of complementation group 8 (CG8, equivalent to CGA). For information on the history of PBD complementation groups, see {214100}.
