In general, many direct-to-consumer DNA tests claim to analyze sleep genes (e.g., CLOCK, PER, CRY), but the evidence for actionable recommendations is weak. Effect sizes of individual SNPs are small, and results vary across ancestries. Studies indicate that polygenic risk scores for sleep disorders explain only a minor fraction of variance (PMID: 38474735). Independent replication is often lacking. Such tests may serve as a rough guide but cannot replace clinical sleep diagnostics. Myths like 'one gene determines your chronotype' are oversimplifications. Fact: sleep is influenced by environment, behavior, and many genes. MyBody-X tests, per context, are not validated for pharmacogenetic or clinical decisions. Therefore, remain critical and avoid overblown expectations.
