[Analysis of point mutations in BRCA1 gene using hybridization on hydrogel microchips].

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).
