Genetics of Parkinson's disease: the yield.
Lausanne, Switzerland. In Parkinsonism Relat Disord, 31 Jan 2014
Monogenic causes include autosomal dominantly (SNCA, LRRK2, VPS35, EIF4G1) as well as recessively (PARK2, PINK1, DJ-1) inherited mutations.
Induced pluripotent stem cell (iPSC)-derived dopaminergic models of Parkinson's disease.
Oxford, United Kingdom. In Biochem Soc Trans, 01 Jan 2014
Given the characteristic loss of dopaminergic neurons in the substantia nigra pars compacta of PD patients, iPSC-derived midbrain dopaminergic neurons have been generated to investigate pathogenic mechanisms in this important cell type as a means of modelling PD. iPSC-derived cultures studied so far have been made from patients carrying mutations in LRRK2 (leucine-rich repeat kinase 2), PINK1 [PTEN (phosphatase and tensin homologue deleted on chromosome 10)-induced putative kinase 1], PARK2 (encodes parkin) or GBA (β-glucocerebrosidase), in addition to those with SNCA (α-synuclein) multiplication and idiopathic PD.
The genetics of Parkinson's disease: progress and therapeutic implications.
Bethesda, United States. In Mov Disord, Jan 2013
Notably, whereas most mutations, such as those in SNCA, PINK1, PARK2, PARK7, PLA2G6, FBXO7, and ATP13A2, are a rare cause of disease, one particular mutation in LRRK2 has been found to be common in certain populations.
Progressive degeneration of human neural stem cells caused by pathogenic LRRK2.
Beijing, China. In Nature, Dec 2012
We decided to evaluate nuclear organization in the context of ageing-associated disorders by focusing on a leucine-rich repeat kinase 2 (LRRK2) dominant mutation (G2019S; glycine-to-serine substitution at amino acid 2019), which is associated with familial and sporadic Parkinson's disease as well as impairment of adult neurogenesis in mice.

α-Synuclein also seems to be linked to other genetic forms of Parkinson's disease, such as those linked to mutations in GBA or LRRK2, possibly through common effects on autophagy and lysosomal function.
