Genes affected

ALOX15 (HGNC:433): (arachidonate 15-lipoxygenase) This gene encodes a member of the lipoxygenase family of proteins. The encoded enzyme acts on various polyunsaturated fatty acid substrates to generate various bioactive lipid mediators such as eicosanoids, hepoxilins, lipoxins, and other molecules. The encoded enzyme and its reaction products have been shown to regulate inflammation and immunity. Multiple pseudogenes of this gene have been identified in the human genome.

The c.1474G>A (p.D492N) alteration is located in exon 11 (coding exon 11) of the ALOX15 gene. This alteration results from a G to A substitution at nucleotide position 1474, causing the aspartic acid (D) at amino acid position 492 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
