Genes affected

LTA4H (HGNC:6710): (leukotriene A4 hydrolase) The protein encoded by this gene is an enzyme that contains both hydrolase and aminopeptidase activities. The hydrolase activity is used in the final step of the biosynthesis of leukotriene B4, a proinflammatory mediator. The aminopeptidase activity has been shown to degrade proline-glycine-proline (PGP), a neutrophil chemoattractant and biomarker for chronic obstructive pulmonary disease (COPD). Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]

The c.467C>A (p.T156N) alteration is located in exon 4 (coding exon 4) of the LTA4H gene. This alteration results from a C to A substitution at nucleotide position 467, causing the threonine (T) at amino acid position 156 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
