Labcorp Genetics (formerly Invitae), Labcorp RCV003771257 SCV001586884 pathogenic not provided 2020-10-09 criteria provided, single submitter clinical testing 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. Disruption of this splice site has been observed in several individuals with clinical features of hereditary leiomyomatosis and renal cell cancer (PMID: 28266706, Invitae). The frequency data for this variant in the population databases is not available, as this variant may be reported as separate entries in the ExAC database. This sequence change affects an acceptor splice site in the last intron (intron 9) of the FH gene. While this is not anticipated to result in nonsense mediated decay, it likely alters RNA splicing and results in a disrupted protein product.
