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.

Identified in a patient with Parkinson disease with unknown family history in the published literature (Paisan-Ruiz et al., 2008); Variant showed reduced Ser910/Ser935 phosphorylation and 14-3-3 binding, and ability of this variant to interact weakly with 14-3-3 isoforms may prevent their accumulation within cytoplasmic pools (Nichols et al., 2010); Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 21885347, 22988870, 24488318, 19800393, 24470158, 19489756, 18973807, 20301387, 18213618, 20642453) -
