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]

The c.725T>A (p.I242N) alteration is located in exon 6 (coding exon 6) of the CYP4A22 gene. This alteration results from a T to A substitution at nucleotide position 725, causing the isoleucine (I) at amino acid position 242 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
