E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Peroxisomal biogenesis disorder Synonym: Zellweger spectrum disorder This syndrome encompasses a spectrum of severity in symptoms
Previously the disorder was subdivided into three disorders based on the severity of symptoms; Infantile Refsum disease (IRD) is the mildest form, neonatal adrenoleucodystrofia (NALD) has more severe symptoms and Zellweger syndrome has the most severe clinical symptoms. |
