In our study, we evaluated the clinical characteristics of 280 patients with <em>CHD7<\/em> mutations and confirmed that the clinical presentation is highly variable. Even family members, who all had the same mutation, were variably affected. We also report some individuals who have very few features of CHARGE syndrome. We conclude that CHARGE syndrome is primarily a clinical diagnosis, but genetic analysis of <em>CHD7<\/em> is helpful in confirming the diagnosis in mildly affected patients. We propose guidelines for <em>CHD7<\/em> analysis and have revised the recommendations for monitoring patients with CHARGE syndrome.
