These tests tell providers about the hearts blood flow and size: Most babies who have Shones complex require surgery soon after birth. CDC twenty four seven. There is no known cure for MCT8 deficiency at this time, although there is on-going research using different forms of thyroid hormone that do not require the MCT8 to enter the cells of the brain. The name "CHOPS" is an abbreviation for a list of features of the disorder including cognitive impairment, coarse facial features, heart defects, obesity, lung (pulmonary) involvement, short stature, and skeletal abnormalities. The result is that patients are born with permanent and severe developmental delay from hypothyroidism (not enough thyroid hormone) in the brain while at the same time they experience hyperthyroidism (too much thyroid hormone) in the rest of their body, leading to intellectual disability, decreased muscle tone, disorganized movements, restless sleep, increased heart rate (tachycardia), failure to thrive/inability to gain weight, and, ultimately, severe infection and cardio-respiratory failure.
