RCV000480830 | SCV000572283 | uncertain significance | not provided | 2016-11-10 | criteria provided, single submitter | clinical testing | This variant is denoted NF1 c.6642-17G>A or IVS43-17G>A and consists of a G>A nucleotide substitution at the -17 position of intron 43 of the NF1 gene. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. In silico models are uninformative, and in the absence of RNA or functional studies, the actual effect of this variant is unknown. NF1 c.6642-17G>A was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. The guanine (G) nucleotide that is altered is not conserved across species. Based on currently available information, it is unclear whether NF1 c.6642-17G>A is pathogenic or benign. We consider it to be a variant of uncertain significance. |

Invitae | RCV000660102 | SCV003471669 | uncertain significance | Neurofibromatosis, type 1 | 2023-06-30 | 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. Studies have shown that this variant is associated with altered splicing resulting in unknown protein product impact (PMID: 32126153). ClinVar contains an entry for this variant (Variation ID: 422739). This variant has been observed in individual(s) with clinical features of neurofibromatosis, type 1 (PMID: 32126153). This variant is not present in population databases (gnomAD no frequency). This sequence change falls in intron 43 of the NF1 gene. It does not directly change the encoded amino acid sequence of the NF1 protein. |
