Genes affected

PTGR1 (HGNC:18429): (prostaglandin reductase 1) This gene encodes an enzyme that is involved in the inactivation of the chemotactic factor, leukotriene B4. The encoded protein specifically catalyzes the NADP+ dependent conversion of leukotriene B4 to 12-oxo-leukotriene B4. A pseudogene of this gene is found on chromosome 1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2009]

Sep 11, 2024

The c.542A>G (p.Y181C) alteration is located in exon 7 (coding exon 6) of the PTGR1 gene. This alteration results from a A to G substitution at nucleotide position 542, causing the tyrosine (Y) at amino acid position 181 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
