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

For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in NF1 are known to be pathogenic (PMID: 10712197, 23913538). This variant has not been reported in the literature in individuals with NF1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Phe1357Serfs*28) in the NF1 gene. It is expected to result in an absent or disrupted protein product.
