Here we report a patient with partial trisomy 2p and congenital dysplasia of the semilunar valves. To our knowledge, this is the first case of 2p duplication with developmental defects of both semilunar valves and suggests that genes on this region contribute to the formation of the semilunar valves.
- Bilateral semilunar valve dysplasia
- Inverted duplication
- Trisomy 2p
