Minor lesion mutational spectrum of the entire NF1 gene does not explain its high mutability but points to a functional domain upstream of the GAP-related domain.

Description

This variant is not present in population databases (ExAC no frequency). For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals with NF1-related conditions. This sequence change creates a premature translational stop signal (p.Leu2258Phefs*5) 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).
