RCV003752787 | SCV004476231 | uncertain significance | Cowden syndrome | 2023-06-22 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PIK3CA-related conditions. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This sequence change falls in intron 2 of the PIK3CA gene. It does not directly change the encoded amino acid sequence of the PIK3CA protein. It affects a nucleotide within the consensus splice site. |
