leucine-rich repeat kinase 1, leucine-rich repeat kinase 2; zinc finger nuclease induced mutant 1, Sigma Advanced Genetic Engineering Labs; This allele was made by ZFN mutagenesis. The resulting mutations are a 19-bp frameshift deletion (TGCCTCGCAGCGGCTGCTG) in exon 4 of Lrrk1 and a 10-bp frameshift deletion (CCCAGAGAGC) in exon 30 of Lrrk2.
