For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. Disruption of this splice site has been observed in individuals with clinical diagnosis or suspicion of neurofibromatosis type 1 (PMID: 10076878, 18546366, 24789688, 30308447). This variant is not present in population databases (gnomAD no frequency). This sequence change affects an acceptor splice site in intron 8 of the NF1 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in NF1 are known to be pathogenic (PMID: 10712197, 23913538).
