Current Research

Adults 17 years and older needed! 

Since the first patient with duplication 17p11.2 was evaluated at Texas Children’s Hospital in 1996, we have had the opportunity to evaluate dozens of children with what is now called Potocki-Lupski syndrome. These clinical and laboratory evaluations have allowed us to publish several articles in the medical literature. These articles are easily accessible to physicians around the world so that they can become more aware of and learn about PTLS and thereby provide better medical and developmental care for children with this chromosomal duplication.….READ MORE…..
