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.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 17, 2023 | This sequence change replaces asparagine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 238 of the LRRK2 protein (p.Asn238Ile). This variant is present in population databases (rs28365216, gnomAD 0.02%). This missense change has been observed in individual(s) with Parkinsons disease, as well as unaffeced individuals (PMID: 21885347, 24565865). ClinVar contains an entry for this variant (Variation ID: 39233). 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) has been performed at Invitae 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. - |
