Below are a collection of excerpts from biomedical research articles. Excerpts are separated by newlines. Your task is to answer a question based these excerpts. Your response should be formatted as a `json` array.

For instance, given excerpts from articles studying breast cancer, and the question "what are some common genes associated with breast cancer?", an answer might be formatted like: ["BRCA1", "BRCA2", "TP53", ...]. Only include answers that are mentioned in the provided exerpts. The array should always have at least one answer; do not respond with an empty array []. Do not include any text in your response other than the answer array.

Context: Mutations in the Parkin gene (PARK2) are the major cause of autosomal recessive early-onset parkinsonism.
Early onset PD (EOPD) is particularly associated with autosomal recessive (AR) mutations, and three genes, PARK2, PARK7 and PINK1, have been found to carry mutations leading to AR disease.
Homozygous or compound heterozygous mutations in the phosphatase and tensin homolog-induced putative kinase 1 (PINK1) gene are causative of autosomal recessive, early onset Parkinson's disease.
Mutations in other genes, including ATP13A2 (PARK9), PLA2G6 (PARK14), and FBX07 (PARK15), cause more rare forms of recessive parkinsonism with very early-onset (<30 years)
In three forms, caused by mutations in parkin (PARK2), PINK1 (PARK6), or DJ-1 (PARK7),
oss-of-function mutations in Parkin, PINK1, DJ-1 and ATP13A2 cause autosomal recessive parkinsonism with early-onset.
mutations in the parkin gene, in DJ-1, PINK1 and ATP13A2 all cause autosomal-recessive parkinsonism of early onset.
mutations in the parkin gene, in DJ-1, PINK1 and ATP13A2 cause autosomal recessive parkinsonism of early onset
Mutations in the parkin gene, in DJ-1 and PINK1 all cause autosomal recessive parkinsonism of early onset.
PTEN-induced putative kinase 1 (PINK1) is a causative gene for autosomal recessive early onset parkinsonism.
we focus on PARK7, a gene relates to an autosomal recessive form of early-onset Parkinsonism and encodes a protein named DJ-1.
PINK-1 for an autosomal-recessive early-onset variant
Heritable mutations in alpha-synuclein, parkin, DJ-1 and PINK1 cause familial forms of PD.
we focus on PARK7, an autosomal recessive form of early-onset parkinsonism caused by mutations in the DJ-1 gene
Mutations in the DJ-1 gene associated with autosomal recessive early-onset parkinsonism.
Autosomal recessive parkinsonism associated with mutations in the parkin gene represents a monogenic form of hereditary parkinsonism.
Mutations of the parkin gene on chromosome 6 cause autosomal recessive, early onset parkinsonism.
A gene causing autosomal recessive parkinsonism of juvenile onset has been mapped to chromosome 6 (PARK 2), and the causative gene has been identified and named parkin.
The gene responsible for AR-JP was recently identified and designated parkin.
