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.

Autosomal dominant Parkinson disease 8 Uncertain:1Other:1

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces arginine with glutamine at codon 1483 of the LRRK2 protein (p.Arg1483Gln). The arginine residue is weakly conserved and there is a small physicochemical difference between arginine and glutamine. This variant is present in population databases (rs113431708, ExAC 0.001%). This missense change has been observed in individual(s) with Parkinson disease (PMID: 18197194). ClinVar contains an entry for this variant (Variation ID: 39190). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
