Pathogenic, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Feb 04, 2021 | The NF1 c.1541_154delAG (p.Gln514ArgfsTer43) variant is a recurrent deletion predicted to result in a frameshift and premature termination or absence of the protein. Across a selection of the available literature, the p.Gln514ArgfsTer43 variant has been identified in at least eight affected individuals in a heterozygous state (Robinson et al. 1996; Sabbagh et al. 2013; Cali et al. 2017). This variant is not found in the Genome Aggregation Database in a region of good sequence coverage, so the variant is presumed to be rare. Based on the predicted truncating nature of the variant and application of ACMG criteria, the p.Gln514ArgfsTer43 variant is classified as pathogenic for neurofibromatosis, type 1. - |

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 12, 2023 | This sequence change creates a premature translational stop signal (p.Gln514Argfs*43) in the NF1 gene. It is expected to result in an absent or disrupted protein product. 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). This premature translational stop signal has been observed in individual(s) with neurofibromatosis type 1 (PMID: 8664912, 17311297, 17914445, 18546366, 25788518, 26969325). ClinVar contains an entry for this variant (Variation ID: 346). For these reasons, this variant has been classified as Pathogenic. - |

Pathogenic, criteria provided, single submitter | clinical testing | ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories | Jan 05, 2019 | The NF1 c.1541_1542delAG; p.Gln514fs variant (rs267606600) is reported in the medical literature in individuals and families affected with neurofibromatosis type 1 (Anastasaki 2015, Anastasaki 2017, Ars 2003, Brems 2009, De Schepper 2008, Hutter 2016, Lin 2018, Noe 2018, Ponti 2016, Pros 2008, Robinson 1996, Wang 2018, Whitworth 2018, Wimmer 2007). This variant is reported as pathogenic by multiple laboratories in ClinVar (Variation ID: 346), and is absent from general population databases (1000 Genomes Project, Exome Variant Server, and Genome Aggregation Database), indicating it is not a common polymorphism. This variant causes a frameshift by deleting 2 nucleotides, so it is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, the p.Gln514fs variant is considered to be pathogenic. References: Anastasaki C et al.
