Summaries for DHODH Gene

Entrez Gene Summary for DHODH Gene

  • The protein encoded by this gene catalyzes the fourth enzymatic step, the ubiquinone-mediated oxidation of dihydroorotate to orotate, in de novo pyrimidine biosynthesis. This protein is a mitochondrial protein located on the outer surface of the inner mitochondrial membrane. [provided by RefSeq, Jul 2008]

    • The identification of DHODH defects as the cause of postaxial acrofacial dysostosis (POADS) was obtained via exome sequencing (PubMed:19915526), demonstrating that this method is a powerful tool for identifying genes underlying rare Mendelian disorders. Exome sequencing consists of targeted resequencing of all protein-coding subsequences, which requires around 5% as much sequencing as a whole human genome.

  • Postaxial acrofacial dysostosis (POADS) [MIM:263750]: POADS is characterized by severe micrognathia, cleft lip and/or palate, hypoplasia or aplasia of the posterior elements of the limbs, coloboma of the eyelids and supernumerary nipples. POADS is a very rare disorder: only 2 multiplex families, each consisting of 2 affected siblings born to unaffected, nonconsanguineous parents, have been described among a total of around 30 reported cases. {ECO:0000269 PubMed:19915526}. Note=The disease is caused by mutations affecting the gene represented in this entry.
