Parkinson’s disease is a brain disorder that may be caused by mutations in several genes that code for the production of alpha-synuclein. Individuals who have Parkinson’s disease exhibit symptoms such as uncontrollable tremors, difficulty walking, and loss of coordination. How might geneticists determine where the mutations that cause Parkinson’s disease are located?
PCR analysis
gene mapping
DNA fingerprinting
STR analysis

Gene mapping.
Explanation: gene mapping (linkage analysis or association studies/GWAS) identifies chromosomal regions associated with the disease in families or populations. Once a region is found, researchers use PCR and DNA sequencing of candidate genes to pinpoint the specific mutations. DNA fingerprinting/STR analysis are for identity/forensics, not for locating disease-causing genes.
