Genes affected

ALOX5AP (HGNC:436): (arachidonate 5-lipoxygenase activating protein) This gene encodes a protein which, with 5-lipoxygenase, is required for leukotriene synthesis. Leukotrienes are arachidonic acid metabolites which have been implicated in various types of inflammatory responses, including asthma, arthritis and psoriasis. This protein localizes to the plasma membrane. Inhibitors of its function impede translocation of 5-lipoxygenase from the cytoplasm to the cell membrane and inhibit 5-lipoxygenase activation. Alternatively spliced transcript variants encoding different isoforms have been identified for this gene. [provided by RefSeq, Feb 2011]

Oct 20, 2023

The c.610A>G (p.I204V) alteration is located in exon 6 (coding exon 6) of the ALOX5AP gene. This alteration results from a A to G substitution at nucleotide position 610, causing the isoleucine (I) at amino acid position 204 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
