INTRODUCTION.
Juvenile Parkinson’s disease (JPD) is a movement disorder that presents before the age of 21 years.
There is evidence that autosomal recessive juvenile Parkinson disease (JPD) is caused by homozygous or compound heterozygous mutation in the parkin (PRKN) gene on cytogenetic location 6q26 and genomic coordinates 6:161,347,417-162,727,766. The screenshot of the PRKN gene 1,380,350 bp (base pairs) of DNA sequence length is shown BELOW. Nine (9) other genes besides PRKN in the 6q26 cytogenetic location are listed BENEATH.
