GeneDx RCV000489844 SCV000577589 uncertain significance not provided 2020-01-09 criteria provided, single submitter clinical testing Not observed in large population cohorts (Lek et al., 2016); Has not been previously published as pathogenic or benign to our knowledge
Invitae RCV000528456 SCV000628741 likely pathogenic Neurofibromatosis, type 1 2020-01-28 criteria provided, single submitter clinical testing This sequence change falls in intron 45 of the NF1 gene. It does not directly change the encoded amino acid sequence of the NF1 protein, but it affects a nucleotide within the consensus splice site of the intron. This variant is not present in population databases (ExAC no frequency). This variant has been shown to segregate with neurofibromatosis type 1 (NF1) in a single family (Invitae). This variant has been also observed in an individual with NF1 in the Leiden Open-source Variation Database (PMID: 23656349). Nucleotide substitutions within the consensus splice site are relatively common causes of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of nucleotide changes on RNA splicing suggest that this variant may alter RNA splicing, but this prediction has not been confirmed by published transcriptional studies. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
