title: [Analysis of point mutations in BRCA1 gene using hybridization on hydrogel microchips].
abstract: Germ-line mutations in BRCA1 gene account for a substantial proportion of inherited breast and ovarian cancers. Identification of these mutations allows molecular diagnosis for breast cancer susceptibility. We have developed method for identification of 185delAG, 300T>G, 4153delA, 4158A>G and 5382insC mutations in BRCA1 gene using hybridization with microarray of geL-immobilized oligonucleotides (microchip). The microchip was tested with 36 control samples, carrying the above-mentioned mutations and 65 clinical cases with breast cancer. Our data demonstrated that developed microchip can be very effective and realible tool, easily introduced in ordinary medical and genetic laboratories.
