Invitae RCV003064421 SCV003442617 pathogenic Neurofibromatosis, type 1 2022-05-05 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 21 of the NF1 gene. RNA analysis indicates that disruption of this splice site induces altered splicing and may result in an absent or disrupted protein product. This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individual(s) with neurofibromatosis type I (PMID: 25480383, 27074763). Studies have shown that disruption of this splice site results in skipping of exon 21 and introduces a premature termination codon (PMID: 27074763). The resulting mRNA is expected to undergo nonsense-mediated decay. For these reasons, this variant has been classified as Pathogenic.
