Which group of individuals is Rett Syndrome primarily associated with?

• A. Males of any age
• B. Female children
• C. Adult men
• D. All genders equally

Answer: (B)

Rett Syndrome is a neurodevelopmental disorder that predominantly affects females, typically manifesting in early childhood. After experiencing a period of normal development, affected girls will typically begin to show a loss of purposeful hand skills and may exhibit repetitive hand movements, loss of communication abilities, and challenges with mobility. The condition is linked to mutations in the MECP2 gene, which is located on the X chromosome. Since females have two X chromosomes, a mutation in one can result in the varied phenotypic expression associated with Rett Syndrome. In contrast, males with a similar mutation often face more severe developmental challenges and typically do not survive past infancy, as they express both the mutated and normal gene due to having only one X chromosome. These genetic factors underscore the condition's strong association with female children specifically.
