Peroxisome biogenesis disorder-4B (PBD4B) includes the overlapping phenotypes of neonatal adrenoleukodystrophy (NALD) and infantile Refsum disease (IRD), which represent milder manifestations of the Zellweger syndrome spectrum (ZSS) of peroxisome biogenesis disorders (PBDs). 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 PEX6 gene have cells of complementation group 4 (CG4, equivalent to CG6 and CGC). For information on the history of PBD complementation groups, see 214100. (614863) (Updated 20-May-2021)
MalaCards based summary : Peroxisome Biogenesis Disorder 4b, is also known as pbd4b, and has symptoms including seizures, ataxia and recurrent fevers. An important gene associated with Peroxisome Biogenesis Disorder 4b is PEX6 (Peroxisomal Biogenesis Factor 6). Affiliated tissues include liver and eye, and related phenotypes are macrocephaly and intellectual disability UniProtKB/Swiss-Prot : 72 Peroxisome biogenesis disorder 4B: A peroxisome biogenesis disorder that includes neonatal adrenoleukodystrophy (NALD) and infantile Refsum disease (IRD), two milder manifestations of the Zellweger disease spectrum. 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. Children with the NALD presentation may reach their teens, while patients with the IRD presentation may reach adulthood. The clinical conditions are often slowly progressive in particular with respect to loss of hearing and vision. The biochemical abnormalities include accumulation of phytanic acid, very long chain fatty acids (VLCFA), di- and trihydroxycholestanoic acid and pipecolic acid. |
