A haptic presentation apparatus includes a base material, an elastic layer, and a fluid transport apparatus. The base material forms a first space and includes a first through hole. The elastic layer covers a surface of the base material including the first through hole. The fluid transport apparatus injects fluid between the elastic layer and the base material via the first through hole. The elastic layer is expanded by injecting the fluid from the fluid transport apparatus such that an internal pressure of a second space between the elastic layer and the base material is higher than an internal pressure of the first space, and the fluid injected into the second space is vented to outside of the second space via a second through hole by stopping driving of the fluid transport apparatus.

A method and evaluation kit are provided, in which a high-capacity urate transporter is identified to assist in the early treatment and prevention of urate transport-related disease and inflammation-related disease. The method can include a step for detecting variations in genes that encode ABCG2 protein. When a subject has an SNP of V12M, R113X, Q126X, Q141K, F208S, G268R, E334X, S441N, L447V, S486N, F506SfsX4, R575X, and/or C608X, it can be concluded that the subject has a factor that is capable of inducing urate transport failure, or a state or disease attributable to that failure. When a subject has an SNP of V12M, it can be concluded that, unlike the other SNPs, there is a possibility that the subject does not possess such a factor because, although this variation itself does not lead to a change in urate transport capability, said variation is related to linkage disequilibrium with other SNPs.
