Can a consumer DNA test interpret ADH1B reliably?

Whether a consumer DNA test can reliably interpret ADH1B depends on what you mean by 'interpret'. ADH1B encodes alcohol dehydrogenase, and well-studied variants like rs1229984 (ADH1B*2) increase enzyme activity, reducing alcohol dependence risk but potentially raising cancer risk. Genotyping of this single nucleotide polymorphism is technically reliable in most consumer tests. However, interpretation is often oversimplified: tests may claim 'fast alcohol metabolism' without explaining ethnic differences, gene-environment interactions, or the lack of clinical cutoffs. The functional evidence for the variant is human-strong, but consumer test interpretation frequently falls into marketing territory. Therefore, while the raw genotype data is usually accurate, the health meaning provided by the test company may be misleading or incomplete. A reliable interpretation requires context from a healthcare professional. Safety note: Do not change alcohol consumption based solely on a consumer test result.
