Abstract
To assess the attitudes of the Japanese general public towards pharmacogenomics research and a DNA bank for identifying genomic markers associated with ADRs and their willingness to donate DNA samples, we conducted a national survey for 1,103 Japanese adults from the general public, not a patient population. The response rate was 36.8%. The majority of the respondents showed a positive attitude towards pharmacogenomics research (81.0%) and a DNA bank (70.4%). Considering fictitious clinical situations such as taking medications and experiencing ADRs, the willingness to donate DNA samples when experiencing ADRs (61.7%) was higher than when taking medications (45.3%). Older generations were significantly associated with a decreased willingness to donate (OR = 0.45, CI 0.28–0.72 in 50s. OR = 0.49, CI: 0.31–0.77 in 60s). Positive attitudes towards pharmacogenomics research, a DNA bank, blood/bone marrow/organ donation were significantly associated with an increased willingness. However, the respondents had the following concerns regarding a DNA bank: the confidentiality of their personal information, the manner by which research results were utilized and simply the use of their own DNA for research. In order to attain public understanding to overcome these concerns, a process of public awareness should be put into place to emphasize the beneficial aspects of identifying genomic markers associated with ADRs and to address these concerns raised in our study. Further study is needed to assess the willingness of actual patients taking medications in real situations, since the respondents in our study were from the general public, not a patient population, and their willingness was assessed on the condition of assuming that they were patients taking medications.

Notes
An adverse drug reaction is noxious, unintended, and occurs at doses normally used in humans (World Health Organization 1971).
