Rhizomelic Chondrodysplasia Punctata, Type 1; Rcdp1

Description

Rhizomelic chondrodysplasia punctata (RCDP) is a peroxisomal disorder characterized by disproportionately short stature primarily affecting the proximal parts of the extremities, a typical facial appearance including a broad nasal bridge, epicanthus, high-arched palate, dysplastic external ears, and micrognathia, congenital contractures, characteristic ocular involvement, dwarfism, and severe mental retardation with spasticity. Biochemically, plasmalogen synthesis and phytanic acid alpha-oxidation are defective. Most patients die in the first decade of life. RCDP1 is the most frequent form of RCDP (summary by Wanders and Waterham, 2005).Individuals with RCDP1, carrying mutations in the PEX7 gene, have cells of peroxisome biogenesis disorder (PBD) complementation group 11 (CG11, equivalent to CGR). For information on the history of PBD complementation groups, see {214100}. Genetic Heterogeneity of Rhizomelic Chondrodysplasia PunctataRCDP2 (OMIM ) is caused by mutation in the gene encoding acyl-CoA:dihydroxyacetonephosphate acyltransferase (GNPAT ) on chromosome 1q42. RCDP3 (OMIM ) is caused by mutation in the gene encoding alkyldihydroxyacetonephosphate synthase (alkyl-DHAP synthase) (AGPS ) on chromosome 2q31. RCDP5 (OMIM ) is caused by mutation in the gene encoding peroxisomal biogenesis factor-5 (PEX5 ) on chromosome 12p13.Whereas RCDP1 is a peroxisomal biogenesis disorder (PBD), RCDP2 and RCDP3 are classified as single peroxisome enzyme deficiencies (Waterham and Ebberink, 2012).
