When Russell was delivered in 2000 via C-section at 36 weeks, 11;29pm, 3 pounds 14 ounces, 16 inches, we were just first time parents with a premie. All the after birth testing was regular, until his blood was checked the following morning. Russell had an extremely low platelet count, and was rushed to another hospital with a better equipped NICU. There, he was given a platelet transfusion which stabilized his count.
During his 4 week stay in the NICU, every bodily system imaginable was tested. It seemed every day we were given a new diagnosis requiring consultation from another specialist. A Cardiologist was needed to monitor the PDA, ASD, and VSD, which closed on their own within the first year without requiring surgery. A Neurologist was brought in to monitor the intracranial brain hemorrhage and polymicrogyria and their effects on his development, or seizure potential. And we were informed about potential long-term neuro-developmental problems. A visit with a Geneticist was scheduled to determine what, if any syndrome he had, in order to know a future prognosis.
Also while in the NICU, Russell would not breast feed or take a bottle, so a Naso-gastric Tube was used for feeding. We had to learn how to place the tube and manage it before we could be released.
Finally, 4 weeks later, we left the hospital as parents with a medically complex child. Russell was delayed in every childhood milestone, and his growth and weight was less than the 5th percentile. His pediatricians always said, “He’ll catch up.” But he didn’t, he set his own pace.
Because he never learned the “suck, swallow, breathe” reflex, we continued with the NG feeding tube for 11 months, but it became very traumatic for me and for Russell. So the Gastroenterologist scheduled surgery to place a Gastrostomy Tube. He still gained weight and length very slowly, and at 27 months, Russell started receiving growth hormone shots. He was almost 8 when he reached the 25th percentile. Shots were discontinued when he was 13 years old because his hand bone age was read as 16 years old.
Shortly before Russell’s 10th birthday, I scheduled him for treatment at Penn State Hershey Feeding Clinic, where we spent a month training Russell to eat. (That is a story in and of itself, which I would be happy to share if anyone wishes to contact me for details.) He has been eating by mouth ever since, although he’s never really enjoyed eating, and meals sometimes last an hour or more.
After years of Genetic testing with no identified syndromes, Russell’s dad and I decided to back off testing for a while. At this point, we realized whatever he had was quite rare, and maybe hadn’t yet been discovered. We knew sometime in the future, as genetic testing improved, an answer would be found.
In 2015, Whole Exome Sequencing (WES) was ordered by his Geneticist. Results came back with a De Novo Mutation of the SON Gene, but it was listed as a “Variant of Unknown Significance”. In 2016, our geneticist was contacted by a researcher at the University of Alabama who was studying the SON Gene and asked if we wanted Russell to be included. The long awaited answer came in September 2016 when the study from the University of Alabama, and a simultaneous study from Baylor University were published in The American Journal of Human Genetics. This research explained the majority of Russell’s symptoms, finally!
It was difficult raising a medically complex child. Friends with typically developing children don’t always know how to respond or act, and sometimes drift away. It can lead to isolation, especially when your child does not have an official diagnosis. I was happy that many of the parents from both studies decided to connect and a Facebook Page, ZTTK-SON SHINE gene DE NOVO was created by 3 of the moms. It was a place to discuss our complex children with people who understood.
Our group has grown to over 200 members in 2021, with a little more than 100 children with the ZTTK Syndrome diagnosis. I am pleased and proud to be a part of creation of the ZTTK SON-SHINE FOUNDATION, Inc., where we hope to further research into the SON gene, and reach and support families of children diagnosed with the syndrome around the world. Most of all, I am proud to be Russell’s Mom!
