Ambry Genetics RCV000167474 SCV000218330 pathogenic Hereditary cancer-predisposing syndrome 2014-12-26 criteria provided, single submitter clinical testing The p.R304* pathogenic mutation (also known as c.910C>T), located in coding exon 9 of the NF1 gene, results from a C to T substitution at nucleotide position 910. This changes the amino acid from an arginine to a stop codon within coding exon 9. This mutation has been observed in multiple individuals meeting clinical diagnostic criteria for NF1 (De Luca, A et al. Hum Mutat. 2004 Jun;23(6):629; Fahsold, R et al. Am J Hum Genet. 2000 Mar;66(3):790-818; Upadhyaya, M et al. Hum Mutat. 2008 Aug;29(8):E103-11; Ko, JM et al. Pediatr Neurol. 2013 Jun;48(6):447-53). In addition to the clinical data presented in the literature, since premature stop codons are typically deleterious in nature, this alteration is interpreted as a disease-causing mutation (ACMG Recommendations for Standards for Interpretation and Reporting of Sequence Variations. Revision 2007. Genet Med. 2008;10:294).
Invitae RCV000468520 SCV000542003 pathogenic Neurofibromatosis, type 1 2020-10-08 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal at codon 304 (p.Arg304*) of the NF1 gene. This variant is not present in population databases (rs786203950, ExAC no frequency). This variant has been reported in the literature in individuals affected with neurofibromatosis, type 1 (PMID: 23668869, 16786508, 23913538, 10862084). ClinVar contains an entry for this variant (Variation ID: 187722). Experimental studies have shown that instead of creating a truncated protein, this variant causes skipping of exon 9 (also known as exon 7 in the literature). This creates a smaller transcript which lacks these codons and is expressed at a decreased amount when compared to wild-type transcript (PMID: 9463322, 10874316). For these reasons, this variant has been classified as Pathogenic.

ARUP Laboratories, Molecular Genetics and Genomics,ARUP Laboratories RCV000508304 SCV000604459 pathogenic not specified 2018-08-15 criteria provided, single submitter clinical testing The NF1 c.910C>T; p.Arg304Ter variant (rs786203950) has been described in several individuals with neurofibromatosis type 1 (NF1) (see link below, Ko 2013, Upadhyaya 2008). It is reported as pathogenic in ClinVar (Variation ID: 187722) and observed on only 1 allele in the Genome Aggregation Database. This variant induces an early termination codon and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, this variant is considered pathogenic.
