Genes affected
DHDH (HGNC:17887): (dihydrodiol dehydrogenase) This gene encodes an enzyme that belongs to the family of dihydrodiol dehydrogenases, which exist in multiple forms in mammalian tissues and are involved in the metabolism of xenobiotics and sugars. These enzymes catalyze the NADP1-linked oxidation of transdihydrodiols of aromatic hydrocarbons to corresponding catechols. This enzyme is a dimeric dihydrodiol dehydrogenase, and it differs from monomeric dihydrodiol dehydrogenases in its high substrate specificity for trans-dihydrodiols of aromatic hydrocarbons in the oxidative direction.

Collection Method: clinical testing

The c.283T>A (p.C95S) alteration is located in exon 3 (coding exon 3) of the DHDH gene. This alteration results from a T to A substitution at nucleotide position 283, causing the cysteine (C) at amino acid position 95 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
