Final answer:
The statement regarding typical intellectual development in individuals with CHARGE syndrome is false; most will have some degree of intellectual disability, but the severity can vary.
Step-by-step explanation:
The statement 'Approximately 30-50% of individuals with CHARGE syndrome have typical intellectual development' is false. CHARGE syndrome is a complex syndrome that involves several birth defects and often includes cognitive and developmental challenges. Although some individuals with CHARGE syndrome may have normal intellectual development, the majority will have some degree of intellectual disability. However, the extent of intellectual disability can vary widely among those affected. It is important to approach each individual case of CHARGE syndrome on a unique basis as symptoms and development can greatly differ among patients.
