METHOD OF DETECTING MUTATION IN HUMAN SEROTONIN RECEPTOR SUBTYPE 2B GENE

摘要

It is intended to provide DNA of a human serotonin receptor subtype 2B gene having a novel mutation. It is also intended to provide a method of detecting a mutation in the human serotonin receptor subtype 2B gene using the novel mutation as described above. Namely, (1) a DNA having a mutation of the base at the 1162-position in the code domain of human serotonin receptor subtype 2B gene into thymine (T); or (2) a DNA being derived from the above DNA by partial modification in a site other than the above base and having such a base length as allowing the detection of the mutation at the above-described base position. A mutation in the human serotonin receptor subtype 2B gene is detected by a method involving the step (a) of analyzing the base at the 1162-position in the code domain of human serotonin receptor subtype 2B gene.
