Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PP5_ModerateBP4BS2_Supporting

The ENST00000244043.5(PTGIS):​c.824G>A​(p.Arg275Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00118 in 1,614,220 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R275W) has been classified as Uncertain significance.

Genes affected
PTGIS (HGNC:9603): (prostaglandin I2 synthase) This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. However, this protein is considered a member of the cytochrome P450 superfamily on the basis of sequence similarity rather than functional similarity. This endoplasmic reticulum membrane protein catalyzes the conversion of prostglandin H2 to prostacyclin (prostaglandin I2), a potent vasodilator and inhibitor of platelet aggregation. An imbalance of prostacyclin and its physiological antagonist thromboxane A2 contribute to the development of myocardial infarction, stroke, and atherosclerosis. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PP5
Variant 20-49524089-C-T is Pathogenic according to our data. Variant chr20-49524089-C-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 208402.Status of the report is criteria_provided_single_submitter, 1 stars.
BP4
Computational evidence support a benign effect (MetaRNN=0.027326822). . Strength limited to SUPPORTING due to the PP5.
BS2
High Homozygotes in GnomAdExome4 at 2 Unknown geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
