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.

The LRRK2 p.Met2408Ile variant was not identified in Clinvitae, Cosmic, MutDB and LOVD 3.0. The variant was identified in dbSNP (ID: rs60545352) and in ClinVar (classified as a VUS for Parkinson disease 8, autosomal dominant by GeneReviews). The variant was also identified in control databases in 6 of 281598 chromosomes at a frequency of 0.000021 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Other in 1 of 7162 chromosomes (freq: 0.00014), Latino in 3 of 35242 chromosomes (freq: 0.000085), European (non-Finnish) in 2 of 128360 chromosomes (freq: 0.000016), but was not observed in the African, Ashkenazi Jewish, East Asian, European (Finnish) and South Asian populations. In a study analyzing LRRK2 variants in patients with familial Parkinson's disease, the p.Met2408Ile variant was identified in one proband with familial PD, but was also found in an unaffected individual from another family and in two healthy control subjects, suggesting this variant does not segregate with disease (Jasinska-Myga_2010_PMID: 20721913). The variant is located in the WD40 protein domain (O.A. Ross_2011_PMID: 21885347), however the p.Met2408 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein. However, this information is not predictive enough to rule out pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
