== Disease ==
[https://www.uniprot.org/uniprot/PYRD_HUMAN PYRD_HUMAN] Defects in DHODH are the cause of postaxial acrofacial dysostosis (POADS) [MIM:[https://omim.org/entry/263750 263750]; also known as Miller syndrome. 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.<ref>PMID:19915526</ref> 
== Function ==
[https://www.uniprot.org/uniprot/PYRD_HUMAN PYRD_HUMAN] Catalyzes the conversion of dihydroorotate to orotate with quinone as electron acceptor.

== Publication Abstract from PubMed ==
Acute myelogenous leukemia (AML), a disease of the blood and bone marrow, is characterized by the inability of myeloblasts to differentiate into mature cell types. Dihydroorotate dehydrogenase (DHODH) is an enzyme well-known in the pyrimidine biosynthesis pathway; however, small molecule DHODH inhibitors were recently shown to induce differentiation in multiple AML subtypes. Using virtual screening and structure-based drug design approaches, a new series of N-heterocyclic 3-pyridyl carboxamide DHODH inhibitors were discovered. Two lead compounds, 19 and 29, have potent biochemical and cellular DHODH activity, favorable physicochemical properties, and efficacy in a preclinical model of AML.
