Genes affected
LRRK2 (HGNC:18618): (leucine rich repeat kinase 2) This gene is a member of the leucine-rich repeat kinase family and encodes a protein with an ankryin repeat region, a leucine-rich repeat (LRR) domain, a kinase domain, a DFG-like motif, a RAS domain, a GTPase domain, a MLK-like domain, and a WD40 domain. The protein is present largely in the cytoplasm but also associates with the mitochondrial outer membrane. Mutations in this gene have been associated with Parkinson disease-8.

This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 286 of the LRRK2 protein (p.Leu286Val). This variant is present in population databases (rs200437744, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with clinical features of Parkinson disease (PMID: 24082139, 26213354). ClinVar contains an entry for this variant (Variation ID: 236286). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on LRRK2 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
