Genes affected
CYP2S1 (HGNC:15654): (cytochrome P450 family 2 subfamily S 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 protein localizes to the endoplasmic reticulum. In rodents, the homologous protein has been shown to metabolize certain carcinogens; however, the specific function of the human protein has not been determined. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.436G>A (p.E146K) alteration is located in exon 3 (coding exon 3) of the CYP2S1 gene. This alteration results from a G to A substitution at nucleotide position 436, causing the glutamic acid (E) at amino acid position 146 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
