Genes affected

ALOX15B (HGNC:434): (arachidonate 15-lipoxygenase type B) This gene encodes a member of the lipoxygenase family of structurally related nonheme iron dioxygenases involved in the production of fatty acid hydroperoxides. The encoded protein converts arachidonic acid exclusively to 15S-hydroperoxyeicosatetraenoic acid, while metabolizing linoleic acid less effectively. This gene is located in a cluster of related genes and a pseudogene that spans approximately 100 kilobases on the short arm of chromosome 17. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

The c.571G>A (p.A191T) alteration is located in exon 4 (coding exon 4) of the ALOX15B gene. This alteration results from a G to A substitution at nucleotide position 571, causing the alanine (A) at amino acid position 191 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
