Illumina Laboratory Services, Illumina RCV001123463 SCV001282304 uncertain significance Neurofibromatosis, type 1 2018-01-12 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV004587046 SCV005076169 uncertain significance not specified 2024-04-15 criteria provided, single submitter clinical testing Variant summary: NF1 c.-51C>T is located in the untranslated mRNA region upstream of the initiation codon. The variant allele was found at a frequency of 0.0001 in 1362378 control chromosomes, predominantly at a frequency of 0.00013 within the Non-Finnish European subpopulation in the gnomAD database. This frequency is not higher than the estimated maximum expected for a pathogenic variant in NF1 causing Neurofibromatosis Type 1 (0.00021), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.-51C>T in individuals affected with Neurofibromatosis Type 1 and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 889509). Based on the evidence outlined above, the variant was classified as VUS-possibly benign.
