Description

This sequence change creates a premature translational stop signal (p.Phe507Leufs*8) in the NF2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in NF2 are known to be pathogenic (PMID: 9643284, 16983642). For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with NF2-related conditions. This variant is not present in population databases (gnomAD no frequency).
