Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2PP2BP4_Moderate
The NM_001042492.3(NF1):c.7553C>A(p.Ala2518Asp) 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 benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A2518T) has been classified as Likely benign.

Neurofibromatosis, type 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 17, 2016 | This sequence change replaces alanine with aspartic acid at codon 2497 of the NF1 protein (p.Ala2497Asp). The alanine residue is weakly conserved and there is a moderate physicochemical difference between alanine and aspartic acid. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a NF1-related disease. In summary, this variant is a novel missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies. - |
