Molecular analysis of the Huntington's disease gene in New Zealand.
To establish and validate a polymerase chain reaction (PCR)-based diagnostic test in New Zealand, which enables the number of CAG repeats present in the Huntington's disease (HD) gene to be determined with speed and accuracy. To develop procedures for reporting and counselling probands and families. ⋯ Our analysis of Huntington's disease alleles has shown a profile of CAG repeat lengths that is consistent with those reported internationally. In addition, reporting and counselling procedures have been established for presymptomatic testing of Huntington's disease in New Zealand.
