Leaves imitate trees: Minnesota Hmong concepts of heredity and applications to genomics research.

Historically, Hmong refugees in the USA were distrustful of Western medicine, medicines, and medical research due to concerns about harm and experimentation. Current Hmong concerns about genomics research are not well known. Our research aims were to identify cultural and ethical issues about conducting genomic studies in the Hmong community. Using a community-based participatory action process, the West Side Hmong Genomics Research Board conducted a qualitative exploratory research study that included semistructured interviews with five Hmong key informants and five focus groups with 42 Hmong adults near Saint Paul, Minnesota. We used a thematic analysis approach to qualitatively analyze the data. Identified concepts of heredity included characteristics that are passed between the generations: physical features; character traits; some behaviors; some diseases; and probably not response to medicines, although individual variations to medicines are known. Most participants were willing to join genomic research projects to help themselves and community. Others refused to participate: they did not want to know future disease risk; did not want doctors to know their genes; did not trust doctors with their blood; and did not know if they would benefit from results. Ethically, many participants were in favor of confidentiality, but wanted to know their personal results; many were willing to agree to genetic storage of anonymous samples; all agreed with individual consent, not family or community consent; and none were concerned about social stigma from genetic testing about chronic diseases and medications. The Hmong Genomics Board will build upon these concepts to create, conduct, and evaluate culturally-appropriate genomic and pharmacogenomic research projects relevant to community interests.
