Description

For these reasons, this variant has been classified as Pathogenic. Nucleotide substitutions within 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 disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has been observed to be de novo in an individual affected with von Hippel-Lindau disease¬†(PMID:¬†8707293). This variant is also known as 677-2A>G in the literature. ClinVar contains an entry for this variant (Variation ID: 223222). This variant is not present in population databases (ExAC no frequency). This sequence change affects an acceptor splice site in the last intron (intron 2) of the VHL gene. While this is not anticipated to result in nonsense mediated decay, it likely alters RNA splicing and results in a disrupted protein product.
