Neurofibromatosis, type 1 Pathogenic:1
For these reasons, this variant has been classified as Pathogenic. While this particular sequence change has not been reported in the literature, truncating sequence changes in NF1 are known to be pathogenic (PMID: 10712197, 23913538). This sequence change deletes 1 nucleotide from exon 9 of the NF1 mRNA (c.1058delT), causing a frameshift at codon 354. This creates a premature translational stop signal (p.Lys354Argfs*22) and is expected to result in an absent or disrupted protein product. -
