Labcorp Genetics (formerly Invitae), Labcorp RCV003815349 SCV004609232 pathogenic Hereditary spastic paraplegia 30; Neuropathy, hereditary sensory, type 2C; Intellectual disability, autosomal dominant 9 2024-01-02 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 372 of the KIF1A protein (p.Leu372Val). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of autosomal dominant KIF1A-related conditions (Invitae). In at least one individual the variant was observed to be de novo. 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 KIF1A protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic.
