| Research Abstract |
The purpose of the current study was to establish comprehensive DNA diagnostic system for various single gene disorders. To this end, we used a novel DNA test strip method to detect previously idertified pathogenic mutations. We also used denaturing high-performance liquid chromatography (DHPLC) to scan for unknown mutations and an automatic capillary DNA sequencer to confirm mutations. The DNA test strip method, originally developed in our laboratory, utilizes competitive allele-specific short oligonucleotide hybridization coupled with immunochromatographic strip. It was used for the detection of known mutations in glycogen storage disease type Ia and Ib, non-ketotic hyperglycinemia, aldehyde dehydrogenase 2 deficiency, Tay-Sachs disease, Gaucher disease, cyctic fibrosis, familial breast cancer due to BRCA1 or BRCA2 mutations, Factor V Leiden mutation, CYP2C19 and mitochondrial A1555G mutation. We also evaluated the feasibility of DHPLC followed by sequencing analysis from clinical diagnostic point of view. The combination of the three methods would facilitate DNA diagnosis by efficiently identifying mutations.
