Variant summary

Our verdict is Benign. Variant got -13 ACMG points: 0P and 13B. BP4_Strong BP6 BS1 BS2

The NM_000962.4(PTGS1):​c.709C>A​(p.Leu237Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0231 in 1,614,078 control chromosomes in the GnomAD database, including 591 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in Lovd as Benign (no stars). Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

Genes affected

PTGS1 (HGNC:9604): (prostaglandin-endoperoxide synthase 1) This is one of two genes encoding similar enzymes that catalyze the conversion of arachidonate to prostaglandin. The encoded protein regulates angiogenesis in endothelial cells, and is inhibited by nonsteroidal anti-inflammatory drugs such as aspirin. Based on its ability to function as both a cyclooxygenase and as a peroxidase, the encoded protein has been identified as a moonlighting protein. The protein may promote cell proliferation during tumor progression. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2021]

PTGS1 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0066508353).
• BP6: Variant 9-122381694-C-A is Benign according to our data. Variant chr9-122381694-C-A is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0181 (2751/152332) while in subpopulation AMR AF= 0.0291 (445/15290). AF 95% confidence interval is 0.0269. There are 38 homozygotes in gnomad4. There are 1290 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 38 SD gene
