Parental Might

The Might family was recently featured in the summer issue of Sanford-Burnham Medical Research Institute's "Portal".  It's a lovely feature on pioneering N-glycanase deficiency research through Dr. Hudson Freeze's laboratory and the Bertrand Might Research Fund.  

According to the Mights, "We began funding Hud's NGLY1 research in mid-2012, and went to visit the lab shortly thereafter in August 2012.  Our fabulous post-doc Ping He has done and continues to do a great job pushing the science for our kids.  We're proud to support the Freeze lab."

NGLY1 Profile: Kaylee, age 4


Patient: Kaylee, age 4
Parents: Kelsey and Daniel
Sibling(s): Justin, age 2



Prenatal:
At about 20 weeks pregnant my OB discovered that Kaylee only had a 2 vessel chord and was a lot smaller that she should be, at the time the chord was thought to be the only reason. We monitered her very closely from that point on. At about 28 weeks I started having twice a week non stress tests (NST's) and weekly ultrasounds. Almost every time I went in for her NST's she showed little or no movement even after they would use the buzzer to try to irritate her, which resulted in ultrasounds to make sure she was ok, she always checked out in these ultrasounds. At 33 weeks she had a large ultrasound at a specialty clinic to get exact measurements and a good estimate of her weight. She had a follow up ultrasound at 37 weeks which showed that she hadn't grown at all between the two. I went to my Dr. appointment directly after that ultrasound and they admitted and induced me that afternoon. After several hours of labor they noticed Kaylee's heart rate drop with each contraction and we had to do an unplanned c-section. She was born 4 lbs 2 oz and 18 in long. Due to her size she was admitted to the NICU and stayed for 8 days. Her lungs were fully developed and she appeared healthy, their only concern at that point was her ability to eat and maintain her own body heat due to her size. She was in an incubator for several of those days and spent 2 days under the billy lights for what they considered mild jaundice. She also had an NG tube placed to help her eat. By the time she was released at 9 days old she was eating on her on and cleared as healthy.


Diagnostic journey:
  At about 10 months of age we started noticing that she was more that a little bit delayed. She was rolling over but not scooting or crawling at all. She also had been very small her whole life, but it had not been concerning because she had been growing on her own consistent curve. At this point she had stopped growing and her pediatrician started showing a lot of concern. At 11 months of age we saw her first specialist, a GI Doctor. She had recommended an NG tube and continuing to a G-tube shortly after. We had to quit Kaylee's breastfeeding cold turkey and move her to formula so we could see exactly how much she was eating. After a few days of this we discovered that she was consistently taking only about 7 oz in an entire day, which is way too little!! At this point we transferred her care to our Seattle Children's hospital so that we could have it all done in one place, and they have fantastic financial aid. We quickly scheduled her NG placement at 11 months of age because of how little she had eaten and the had dropped for about 16 lbs to about 14lbs. Her weight showed immediate improvement from the NG tube. At the time she also had blood drawn and showed elevated liver functions and low white blood counts. About a year later we placed a G tube and she is still on this today.

  Soon after seeing her GI Dr. we started seeing a biochemical geneticist and a variety of other Dr.'s. Her geneticist suspected she had a mitochondrial disorder. She was pretty quickly tested for several of the more common ones via blood tests, and had a brain MRI, muscle biopsy and liver biopsy all at one time when she was about 15-18months old (I don't remember her exact age). Her MRI and muscle biopsy were clear, but her liver biopsy showed some cirrhosis of the liver, and at the time they told us she might eventually need a liver transplant. Since then her liver functions have continued to stay about the same and they no longer believe a transplant is likely to become necessary. As well all of the blood tests we did over the next 1 1/2 years came back negative for all known mitochondrial disorders they could test for. We had discussed at about 3 years of age a whole exome sequencing test but they were having some problems requesting them and at this point her Dr. thought that anything we found out would be informational and have no treatment so we held off on the testing for a while. We did her test in April of 2013 and got her results in September (almost 4 years of age, 3 years after we began testing) which showed she had mutated NGLY1 genes which her doctor knew nothing about. He did some research and in December we were referred to Dr. Hudson Freeze and from there we were able to meet Cristina and several other families. 

    In the mean time off all the big tests we also did hearing tests which came back normal, an eye exam which showed that her sight was normal. We did swallow studies, liver ultrasounds, bone age X-rays, hip and spine X-rays and countless blood tests to continue to check her liver functions and white blood cell and platelet counts. Which were both low at some points but normalize at times. We discovered that her spleen is destroying her platelets, which we still are not sure why but believe it's because her spleen is working too hard because her liver isn't functioning properly, we have discussed the possibility of needing a stint to be placed to bipass her liver if her spleen continues to be enlarged and work too hard.


Symptoms:
Kaylee has had:
elevated liver functions
low white cell counts
low platelet counts
cirrhosis of the liver
enlarged spleen 
very low production of tears
lack of muscle tone

Physical delays:
crawls (started at about 2 yrs of age)
pulls up to stand 
takes some steps with the use of a gait trainer (walker)
Is just beginning to try to use an ipad for communication, she has no words
She has very poor fine motor skills, has difficulty with purposeful movements to complete a task
She also uses foot braces for very tight heal chords, significantly tighter in her left foot.

NGLY1 Profile: Tim, age 3


Patient: Tim*, age 3
Parents: C and A
Sibling(s): none


"Tim" was born in June 2011 by Cesarean section at 39 weeks after fetal distress was noted.  He weighed only 2.3 kg at birth - intrauterine growth restriction (IUGR) had been noted at around 34 weeks of pregnancy and a biopsy of the placenta showed necrotic tissue. He had mild hyperbilirubinemia which did not require treatment, but otherwise his neonatal course was unremarkable and we were discharged on day three.


It was not long after that our journey began. Something seemed not right with Tim. He was crying inconsolably, not sleeping well, he moved different from other babies, he could not hold up his head very well (and he kept on nodding – we only realized much later that those nods were seizures! No doctor had picked it up). He was floppy and lying in a C-shape. He did not like to be touched or soothed. He did not like noisy environments or other people in general. He was fussy. Somehow he always managed to reach his milestones just in time in those first months and since he was feeding well, no doctor got concerned. They always sent us home with words of encouragement such as “all babies are bad sleepers” or “some boys tend to develop more slowly” but we just KNEW that something was not right!


At 6 months we took him to a neurologist and she immediately confirmed our worst fears. Our son had “brain damage” and no, there was nothing we could do but try to ease the symptoms and carry on with our lives. We were devastated! We got Tim admitted to a big university hospital in Germany and all sorts of tests were done. It was so scary and unreal. Many results came back slightly abnormal (one of them was for CDG which in the end happened to be a close match to NGLY1 deficiency), but it was all unspecific and we were discharged with no diagnosis and even more fear than before. We had:
  • global developmental delay
  • generalized poly-spike discharges in the EEG
  • elevated blood lactate levels
  • elevated LFTs
  • delayed myelination in the MRI


Soon after, Tim’s seizures started to get worse (we are pretty sure they had been there before) we started a long journey of finding the right medication. This journey led Tim to another hospital stay of almost two months. He had myoclonic jerks of arms and legs and nodded with his head (atonic seizures). We kept close track of the frequency. What started out with 20 seizures a day went up to 200 while the doctors kept changing his meds again and again. Tim was miserable. He got worse from day to day. He could barely move anymore and stopped smiling. The doctors started telling us that “this was the nature of his progressive disease”. A second MRI showed his brain was shrinking. It was horrifying.


Somehow, for lack of a better idea, doctors declared him to be a suspected case of mitochondrial disease. As one doctor put it “this is the only label under which we can combine the EEG and the liver findings”. We were so frustrated with these doctors and the hospital in general!


After some months we took him out of the hospital and off the meds, but we still had no diagnosis and no idea where we were headed. We started to note involuntary movements and Tim kept on getting eye infections which resulted in corneal scarring – we first blamed the high-dose steroid therapy while actually these were fundamental symptoms of his disease. He could not close his eye lids during sleep. He was severely constipated. His sleep pattern was highly pathological with hardly any deep sleep and many arousals during the night. He was constantly tired, and so were we.


On the positive side, time showed that his regression during the hospital stay was not due to his progressive disease but due to the treatment. The longer Tim was out of the hospital the more he recovered. A new MRI in spring 2013 – although still showing abnormal results like the first one – showed that Tim’s brain had re-gained its volume. We started milder interventions for treating the epilepsy like the ketogenic diet and phased meds in and out very slowly and not as abruptly as in the hospital. Still, except for Lamictal more than a dozen medications showed no effect or only negative side-effects. Lamictal helped at least a little bit with his sleep and mood. Tim’s greatest motor achievement during that time was learning to belly crawl a few months before his second birthday.


In the summer of 2013, briefly before his second birthday, I did an internet search for “ketogenic diet check up protocols” and found Cristina’s blog. I saw pics of Bertrand and immediately started reading about his symptoms. He looked and sounded so much like Tim!!! So I sent the Mights an email and received a reply the same day. We were so excited! They too thought Tim was a close match and put us in touch with their doctors. We sent his skin cells and DNA to the States and bam…a few weeks later we had a diagnosis! Tim was the first child to be only tested for NGLY 1 deficiency (and not whole exome/genome sequencing) and the 10th child to receive the diagnosis. He is the only German child so far.  


Having a diagnosis has changed everything. We are no longer alone, but are in this together with some of the most wonderful families imaginable. The exchange between the families has been tremendously helpful and I am sure will continue to be so as we are working on finding a cure. Also, based on Bertrand’s experience and because we had run out of other options we were able to convince our doctors to put Tim on Valproate for his seizures (they had not dared to do so earlier because of his suspected mitochondrial disease). It took a long while (almost 6 months and increase up to 600 mg/day), but he became seizure free. He has been seizure free for more than three months now (knock on wood). He is a changed child. He has learned to sit up, to come on his hands and knees, to feed himself, and to take supported steps during this time. He babbles the whole day, and is so much happier and calmer than before.


Overcomingmovementdisorder.com” has changed our lives and we’ll be eternally grateful to Cristina and Matt. We want to encourage all parents to never give up the search for a diagnosis – even if there is no cure yet, it can make a huge difference in your child’s and your own quality of life!

Background:
- Proteins, fats, and other molecules are the body s building blocks. Many of these molecules must have sugars, or chains of sugars, attached to work properly. People with congenital disorders of glycosylation (CDGs) cannot attach these sugars or sugar chains properly. A child or adult with a CDG can have symptoms in different parts of the body, including brain, nerves, muscles, liver, and immune system. Researchers want to learn more about these diseases to understand better what is causing the problems.
Objective:
- To learn more about CDGs.
Eligibility:
- People age 1 80 with CDG or suspected to have a CDG.
Design:
-CDG participants will stay in the hospital 3 5 days. They will have:
-Medical history and physical exam. They will answer questions about their CDG.
-Blood taken several times. Their skin will be numbed, then a needle will take blood from an arm vein.
-Samples taken of their skin, urine, and maybe stool and spinal fluid.
-Photos taken of their whole body. They can wear underwear and cover their eyes.
-Brain MRI. They will lie on a table that slides in and out of a metal cylinder. The scanner makes loud knocking noises so they can wear earplugs.
-Abdomen ultrasound. Sound waves take images of the body from the outside.
-Hand/wrist X-rays for young patients. They may have a full-body X-ray.
-DEXA bone density scan. Participants will lie on a table under a scanner.
-Echocardiogram and electrocardiogram for heart activity. Pads are stuck on the skin and the electrical activity of the heart is recorded.
-Tests of hearing, thinking, motor skills, and speech.
- Children participants may have tests done under sedation if it will benefit them directly.
- CDG participants may have other procedures during their visit. They may have follow-up visits every year.

Eligibility

INCLUSION/EXCLUSION CRITERIA:
Patients of any gender and ethnicity age 1-80 years with a suspected CDG based on biochemical tests or a confirmed CDG based on enzymatic or molecular tests will be eligible to enroll in this protocol. Patients will also be excluded if they cannot travel to the NIH due to their medical condition. Infants under age one year or under 10 kg of body weight are excluded because care is more readily provided to older infants at the Clinical Center.
