Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The NM_001146108.2(PTGR1):c.282C>G(p.His94Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000216 in 1,614,054 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H94Y) has been classified as Uncertain significance.

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]

Ambry Genetics

Dec 18, 2023

The c.282C>G (p.H94Q) alteration is located in exon 5 (coding exon 4) of the PTGR1 gene. This alteration results from a C to G substitution at nucleotide position 282, causing the histidine (H) at amino acid position 94 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
