RCV001209023 | SCV001380442 | pathogenic | Neurofibromatosis, type 1 | 2023-08-10 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 939599). This variant is also known as c.2835_2836insT (p.Phe944fs, PTC946). This premature translational stop signal has been observed in individual(s) with clinical features of neurofibromatosis type 1 (PMID: 16835897). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Asp946*) 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). |
Ambry Genetics | RCV004557414 | SCV005047623 | pathogenic | Hereditary cancer-predisposing syndrome; Cardiovascular phenotype | 2023-10-16 | criteria provided, single submitter | clinical testing | The p.D946* pathogenic mutation (also known as c.2835dupT), located in coding exon 21 of the NF1 gene, results from a duplication of T at nucleotide position 2835. This changes the amino acid from an aspartic acid to a stop codon within coding exon 21. This alteration was observed in 1 of 77 Taiwanese/Chinese patients with suspected clinical features of NF1 (Lee MJ et al. Hum Mutat, 2006 Aug;27:832). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. |
