Ambry Genetics RCV002445184 SCV001189676 uncertain significance Hereditary cancer-predisposing syndrome; Cardiovascular phenotype 2019-12-11 criteria provided, single submitter clinical testing The c.8097+4A>G intronic variant results from an A to G substitution 4 nucleotides after coding exon 55 in the NF1 gene. This nucleotide position is well conserved in available vertebrate species. Using two different splice site prediction tools, this alteration is predicted by ESEfinder to weaken the efficiency of the native splice donor site, but is not predicted to have a deleterious effect on this splice donor site by BDGP; however direct evidence is insufficient at this time (Ambry internal data). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Invitae RCV001862402 SCV002198920 uncertain significance Neurofibromatosis, type 1 2023-04-19 criteria provided, single submitter clinical testing In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Variants that disrupt 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 is not likely to affect RNA splicing. ClinVar contains an entry for this variant (Variation ID: 827445). This variant has not been reported in the literature in individuals affected with NF1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change falls in intron 55 of the NF1 gene. It does not directly change the encoded amino acid sequence of the NF1 protein. It affects a nucleotide within the consensus splice site.
