Study Notes
Developmental Regression in a 3-year-old Girl
- A 3-year-old girl is brought to the pediatrician due to developmental regression, having previously met developmental milestones but now showing a loss of acquired skills.
- The child exhibits stereotypical hand movements, including wringing and washing, indicating a potential neurological disorder.
- There is a loss of purposeful hand skills, suggesting a decline in fine motor abilities.
- Deceleration in head growth compared to peers is a notable physical finding, indicating a possible neurodevelopmental disorder.
- Genetic testing reveals a mutation in the MECP2 gene, a key indicator of a specific genetic disorder.
- The combination of symptoms and genetic mutation points to a likely diagnosis of Rett syndrome.
