    The Genetic Key to a beautiful life 
full of possibilities

     Welcome to Potocki-Lupski Syndrome Outreach Foundation, Inc, a non-profit 501(c)(3), a place for support, advice, guidance, and family interaction. PTLS is a rare chromosome Duplication of 17p11.2 that is predicted to reach 1 in 20,000 children. When the first child in the United States was diagnosed with Potocki-Lupski Syndrome, in 1991, and studied in 1996, very little was known about duplication 17p11.2, many questions and very few answers. As more children are being diagnosed, we see there are many similarities, with some variations. This duplication has a spectrum of symptoms and characteristics, found in both boys and girls. Some of the children have a small area duplicated, others with a larger band of duplication. Some children have other chromosomal differences as well. These variations will present themselves in various health and developmental issues. 
    One thing we do know, is that these beautiful children are happy, full of life, and filled with talents that may seem hidden, but given time and maturity, they will show themselves. Patience and time to mature brings about many wonderful developments. Celebrate your child for who they are, and know life will be ever changing for them. Through the tears of some of the challenges, great joy will shine through.

What is PTLS?:

Potocki-Lupski syndrome (PTLS), also known as dup(17)p11.2p11.2 syndrome, trisomy 17p11.2 or duplication 17p11.2 syndrome, is a microduplication involving the 11.2 band on the short arm (upper arm) of the human chromosome 17 (17p11.2).  The RAI1 gene plays a big part in the characteristics of PTLS. Some children have a added syndrome, called Charcot-Marie-Tooth (CMT, or 1A (CMT1A), which is a hereditary demyelinating peripheral neuropathy, associated with a DNA duplication on chromosome 17p12, The region next to the 17p11.2, known as Potocki-Lupski Syndrome.

The duplication was first described as a  case study
in 1996.  Then, in 2000, the first study of the disorder was released, and in 2007, enough patients had been gathered to complete a comprehensive study, which gave it a detailed clinical description. World reknown geneticist, Dr. James Lupski, has established a mouse model lab to help continue studying the behaviors and health issues connected to this duplication. Potocki-Lupski Syndrome finally got its official name, in March of 2007. The first Potocki-Lupski Syndrome Family Conference was held in 2009, which discribed, in deatail, all the research findings need to understand a great majority of what PTLS is. Due to the difficulty in testing for this in the past, there have been just a few adults diagnosed with this, therefore, limiting the studies to children. Now with the newer testing, called Microarray, the doctors can now diagnose those adults and children who would have been missed in the past. With the growing number of adults being diagnosed, we can now get a bigger picture of what the future holds for the children.
PTLS is named for two researchers involved in the latter phases, Drs. Lorraine Potocki and James R. Lupski 
of the Baylor College of Medicine in Houston, Texas.


As parents of unique children, we believe they have the potential of achieving success in achieving their goals, and making a great impact on this world.

A note from Julie:
My wonderful parents,
    Please see life through your child's eyes, for it is a beautiful sight, so full of love. As the mother of the first child, now 23 years old, I have lived this life with tears, fears and heartwarming laughter. I have seen this journey make its way, not only through my child's eyes, but through those of many unbelievable children with PTLS, who have gently guided us parents, unknowingly,through our struggles and challenges with this rare duplication. They watch us with confidence that we will eventually learn what they already know. These children have the greatest amount of patience for us parents who love them so
    None of us asked for this path in life, but it is the one we were placed on. Years ago, I wondered if I was on the right path and if I would ever make it down the path. I now can tell you, I have made it down that path, and when I learned to stop and smell the roses, I normally would of trampled on, I found it to be a path I am blessed to have been put on. Just when I thought I have seen the last tree, the last flower, and ready to get off the path, I am pulled back and reminded that I am on a special journey, with a very special young man. Thank you, Christian!
    When the tears begin to dry, and you have moved through the stages of grief that comes with this, you too will see that you have been lead through a magnificent journey, shared by the chosen few, and guided by a very special angel, your child. 
    So until you reach you journey's end, please know you are a part of a wonderful group of families who have bonded together, in loving support. Our wonderful PTLS community is here to welcome you with open arms. You are not alone!

Meet Our Advisory Board

James R. Lupski, M.D., Ph.D. D. Sc. (hon)
The Cullen Endowed Chair in Molecular Genetics
Professor, Department of Molecular and Human Genetics

Vice chair professor of molecular and human genetics and pediatrics at Baylor College of Medicine in Houston. Lupski, also director of the Medical Scientist Training Program and American Editor of Neurogenetics, received his B.A. in 1979 and Ph.D. in 1984, both from New York University. He received his M.D. from New York School of Medicine in 1985.

He went on to complete his postdoctoral work at New York University in 1986 and completed a residency in pediatrics and fellowship in medical genetics at Baylor College of Medicine.

Lupski's research interests include determining the molecular mechanisms for disease using human genetic approaches to investigate clinical phenotypes. A major focus is the molecular genetics of Charcot-Marie-Tooth (CMT) disease and related inherited demyelinating peripheral neuropathies. Additional efforts are aimed at determining the molecular mechanism for contiguous gene syndromes. Other human genetic disease gene mapping research involves collaborative efforts with Dr. Richard A. Lewis to map rare, recessively inherited eye disorders.

Lupski's work has appeared in such publications as Science, Annals of Neurology and Nature Genetics.
