Wilsons Disease Statistics

Wilson disease affects about 1 in 30,000 people, yet among unexplained pediatric liver disease it accounts for roughly 1 to 2 percent, and in acute liver failure it drives about 2 to 3 percent of cases. Learn why the timeline matters too, with a median delay to diagnosis of 2.5 years and outcomes improving substantially when treatment starts early, backed by global prevalence estimated at about 3.3 per million and incidence at about 0.6 per million person years from a 2019 systematic review.

Wilson disease may affect just 1 in 30,000 people in the general population, yet it explains about 2 to 3% of acute liver failure cases and up to 1 to 2% of unexplained pediatric liver disease. The puzzle is that the earliest signs can look like something else, and even after symptoms begin, diagnosis often takes years. In this post, we pull together the most useful global and clinical Wilson disease statistics, from ATP7B carrier rates and Leipzig scoring patterns to how often neurologic, hepatic, and psychiatric symptoms show up at presentation.

Diagnosis & Care Interpretation

Across cohorts and guideline-based practice, about half of patients with neurologic Wilson disease improved after chelation while long-term liver transplant outcomes remained strong with roughly 85 to 90% survival at 1 year and 75 to 85% at 5 years, underscoring that treatment success depends heavily on early effective management and sustained monitoring.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point.
