Therefore, it has been classified as a Variant of Uncertain Significance. This sequence change falls in intron 3 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. This variant is present in population databases (rs200507422, gnomAD 0.06%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with PIK3CA-related conditions. ClinVar contains an entry for this variant (Variation ID: 567701). 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 is not likely to affect RNA splicing.
