Ambry Genetics | RCV002445178 | SCV001189619 | likely pathogenic | Hereditary cancer-predisposing syndrome; Cardiovascular phenotype | 2018-01-19 | criteria provided, single submitter | clinical testing | The c.8050+2T>G intronic variant results from a T to G substitution two nucleotides after coding exon 54 in the NF1 gene. This nucleotide position is highly conserved in available vertebrate species. Using the BDGP and ESEfinder splice site prediction tools, this alteration is predicted to abolish the native splice donor site; however, direct evidence is unavailable. Alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is classified as likely pathogenic. |

RCV001862397 | SCV002225283 | pathogenic | Neurofibromatosis, type 1 | 2021-11-12 | criteria provided, single submitter | clinical testing | This sequence change affects a donor splice site in intron 54 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). 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 1 (Invitae). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 827420). Studies have shown that this variant is associated with altered splicing, but the impact on the resulting protein product is unknown (Invitae). For these reasons, this variant has been classified as Pathogenic. |
