Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PM5PP2PP3_ModeratePP5_Moderate
The NM_001042492.3(NF1):c.3578T>G(p.Phe1193Cys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 13/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F1193I) has been classified as Likely pathogenic.

Neurofibromatosis, type 1 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Mar 04, 2022 | ClinVar contains an entry for this variant (Variation ID: 68335). For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Phe1193 amino acid residue in NF1. Other variant(s) that disrupt this residue have been observed in individuals with NF1-related conditions (PMID: 28961165; Invitae), which suggests that this may be a clinically significant amino acid residue. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NF1 protein function. This missense change has been observed in individual(s) with neurofibromatosis (PMID: 11735023). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces phenylalanine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 1193 of the NF1 protein (p.Phe1193Cys). - |
