Description

In the published literature, the variant has been reported individuals with hereditary breast and ovarian cancer (PMID: 29928469 (2018) and 21120943 (2011)). Published studies indicate that this variant does not alter splicing (PMID: 32641407 (2020), 32123317 (2020)) and does not demonstrate allelic imbalance (PMID: 19471317 (2009)). The frequency of this variant in the general population, 0.00014 (5/34570 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded conflicting predictions that this variant is benign or damaging. Based on the available information, we are unable to determine the clinical significance of this variant.

Description

In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 21120943, 19471317, 25348012, 29659569, 29928469, 32641407, 32123317)

Description

The p.Pro94Ser variant was identified by Caux-Moncoutier (2009) in a hereditary breast/ovarian cancer (HBOC) patient. The authors of this study used an allelic imbalance assay to assess the putative impact of variants on splicing; no allelic imbalance was found for the variant, suggesting that it does not impact splicing. The variant was also identified in dbSNP (ID: rs80358531) â€šÃ„ÃºWith non-pathogenic alleleâ€šÃ„Ã¹, and three times in UMD as an unclassified variant. The p.Pro94 residue is conserved across mammals and lower organisms and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM) suggest that the p.Pro94Ser variant may impact the protein. However, this information is not predictive enough to assume pathogenicity. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of unknown significance.
