Genes affected
CYP4A22 (HGNC:20575): (cytochrome P450 family 4 subfamily A member 22) 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 gene is part of a cluster of cytochrome P450 genes on chromosome 1p33. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Apr 2015]
CYP4A22-AS1 (HGNC:43715): (CYP4A22 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 05, 2023The c.731G>A (p.S244N) alteration is located in exon 6 (coding exon 6) of the CYP4A22 gene. This alteration results from a G to A substitution at nucleotide position 731, causing the serine (S) at amino acid position 244 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
