Rhizomelic chondrodysplasia punctata

Rhizomelic chondrodysplasia punctata (RCDP) is one of the most severe peroxisomal disorders, characterized by skeletal abnormalities and impaired development. It is primarily caused by mutations in the PEX7 gene.

The PEX7 gene is responsible for producing a receptor protein involved in the transport of proteins into peroxisomes, which are cell structures involved in various metabolic functions. Mutations in this gene can lead to a nonfunctional or partially functional receptor, resulting in the accumulation of phytanoyl-coa and other fatty acids in certain tissues. This accumulation leads to the characteristic symptoms of RCDP, including skeletal abnormalities and developmental delays.

RCDP1 is the most common form of this condition, and it is inherited in an autosomal recessive manner. The condition is named after the characteristic skeletal changes observed in affected individuals, including shortening and thickening of the long bones in the limbs (rhizomelia) and abnormal development of the cartilage (chondrodysplasia).

Diagnosis of RCDP can be confirmed through genetic testing, which can identify mutations in the PEX7 gene. This testing can be done through various resources, including genetic testing laboratories and specialized genetic databases. The GeneReviews® and OMIM databases provide additional information on this condition, including variant names, testing information, and related scientific articles.

The National Center for Biotechnology Information’s PubMed database also contains a catalog of scientific articles on RCDP and related conditions. The PEX7 gene is listed in various databases, such as OMIM, GeneReviews®, and PubMed, which provide information on the gene’s function, genetic changes associated with RCDP, and additional resources for testing and research.
