Involvement in diseasei

Peroxisome biogenesis disorder complementation group 11 (PBD-CG11)

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA peroxisomal disorder arising from a failure of protein import into the peroxisomal membrane or matrix. The peroxisome biogenesis disorders (PBD group) are genetically heterogeneous with at least 14 distinct genetic groups as concluded from complementation studies. Include disorders are: Zellweger syndrome (ZWS), neonatal adrenoleukodystrophy (NALD), infantile Refsum disease (IRD), and classical rhizomelic chondrodysplasia punctata (RCDP). ZWS, NALD and IRD are distinct from RCDP and constitute a clinical continuum of overlapping phenotypes known as the Zellweger spectrum (PBD-ZSS).

Rhizomelic chondrodysplasia punctata 1 (RCDP1)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA peroxisome biogenesis disorder. It is characterized by rhizomelic shortening of femur and humerus, vertebral disorders, cataract, cutaneous lesions and severe mental retardation.

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA peroxisome biogenesis disorder with unusually mild clinical and biochemical manifestations. Affected individuals manifest a variable phenotype similar to, and in some cases indistinguishable from, classic Refsum disease. Variable features include ocular abnormalities, sensorimotor neuropathy, ichthyosis, deafness, chondrodysplasia punctata without rhizomelia or growth failure.
