Genes affected

DHODH (HGNC:2867): (dihydroorotate dehydrogenase (quinone)) 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 c.178C>G (p.R60G) alteration is located in exon 2 (coding exon 2) of the DHODH gene. This alteration results from a C to G substitution at nucleotide position 178, causing the arginine (R) at amino acid position 60 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
