Genes affected
CYP26C1 (HGNC:20577): (cytochrome P450 family 26 subfamily C member 1) This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This enzyme is involved in the catabolism of all-trans- and 9-cis-retinoic acid, and thus contributes to the regulation of retinoic acid levels in cells and tissues. This gene is adjacent to a related gene on chromosome 10q23.33. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2022The c.407A>G (p.E136G) alteration is located in exon 2 (coding exon 2) of the CYP26C1 gene. This alteration results from a A to G substitution at nucleotide position 407, causing the glutamic acid (E) at amino acid position 136 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
