(2010) Genetic testing for Huntington's Disease in Parkinsonism. Mymensingh Medical Journal, 19 (4). pp. 510-514.


The study was conducted to find out Huntington's disease (HD) by genetic analysis from those presenting with parkinsonism in the Neurology department of Mymensingh Medical College & Hospital. A sample of about 5ml blood was collected by veni puncture in EDTA tube with informed consent from 9 patients & 7 healthy individuals after approval of the institutional ethics committee for genetic study. The neurological disorder along with a complete history and physical findings were recorded in a prescribed questionnaire by the neurologists of Mymensingh Medical College & Hospital. Extraction of genomic DNA from the venous blood using FlexiGene DNA kit (Qiagen, Japan) was performed in Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh, Bangladesh. The extracted DNA was stored and accumulated and then these DNA were sent to Division of Clinical Genetics, Department of Medical Genetics, Osaka University Medical School, Suita, Osaka 565 0871, Japan for PCR and further analysis. PCR amplification of the CAG repeat in the 1T15 gene was performed with primers HD1 and HD3. HD PCR products revealed the DNA product of about 110bp (no. of CAG repeats=21) to 150bp (no. of CAG repeats=34) in both healthy individual and suspected PD patient DNA.
