Outline of Final Research Achievements

Genetic diseases are usually caused by mutation of each responsible gene, but some genetic diseases are caused by epigenetic mechanism.
This research aimed at obtaining new knowledge of pathogenesis through single cell expression analysis using RNA-FISH method which allow distinguish the homologous chromosomes.
As one of the target diseases, we selected the structural X chromosome abnormalities in female. We succeeded in 3-color RNA-DNA FISH method using RNA probe for XIST gene, DNA probes for the reference region and for the target region mapped all on the X chromosome, which can detect X chromosome inactivation pattern and normal/abnormal X chromosome simultaneously in each individual nucleus. And the results of this study for the carrier females as the subjects confirmed the usefulness of this procedure, since the X chromosome inactivation pattern were consistent with the result using the another X chromosome inactivation analysis.
