Genes affected
CYP4X1 (HGNC:20244): (cytochrome P450 family 4 subfamily X member 1) This gene encodes a member of the cytochrome P450 superfamily of enzymes and is located within a cluster of genes belonging to this superfamily on chromosome 1. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. The expression pattern of a similar rat protein suggests that this protein may be involved in neurovascular function in the brain. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 06, 2024The c.736C>T (p.R246C) alteration is located in exon 6 (coding exon 6) of the CYP4X1 gene. This alteration results from a C to T substitution at nucleotide position 736, causing the arginine (R) at amino acid position 246 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
