The neonatal form of adrenoleukodystrophy (NALD) and Infantile Refsum disease (IRD) are milder form of Zellweger syndrome spectrum (ZSS) disorders. They are caused by defects in one of PEX genes, which encode proteins involved in peroxisome assembly and proliferation. 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 vision impairment.
