Labcorp Genetics (formerly Invitae), Labcorp RCV000225802 SCV000284437 pathogenic Neurofibromatosis, type 1 2023-10-17 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1219 of the NF1 protein (p.Gly1219Val). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of neurofibromatosis type 1 (Invitae). ClinVar contains an entry for this variant (Variation ID: 237552). 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 variant disrupts the p.Gly1219 amino acid residue in NF1. Other variant(s) that disrupt this residue have been observed in individuals with NF1-related conditions (PMID: 31573083; Invitae), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic.
