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	Labcorp Genetics (formerly Invitae), Labcorp	Dec 23, 2021	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. 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. ClinVar contains an entry for this variant (Variation ID: 236296). This missense change has been observed in individual(s) with LRRK2-related conditions (PMID: 23726462, 26213354). This variant is present in population databases (rs200002022, gnomAD 0.01%). This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 2310 of the LRRK2 protein (p.Thr2310Met). -
Uncertain significance, no assertion criteria provided	literature only	GeneReviews	Dec 11, 2014	- -
Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 28, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign. -

Variant summary: LRRK2 c.6929C>T (p.Thr2310Met) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 6e-05 in 251130 control chromosomes. c.6929C>T has been reported in the literature in individuals affected with Parkinson Disease 8, Autosomal Dominant. These reports do not provide unequivocal conclusions about association of the variant with Parkinson Disease 8, Autosomal Dominant. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 25174650, 22415848, 38137339, 23726462). ClinVar contains an entry for this variant (Variation ID: 236296). Based on the evidence outlined above, the variant was classified as uncertain significance. -
