Mutations in the AFF4 gene are thought to result in an AFF4 protein that is not broken down when it is no longer needed, so more AFF4 protein is available than usual. Families of children with TBCK have found that patients tend to run higher already due to hypotonia and muscle weakness. Using samples from all three children, his research team made the groundbreaking discovery back home in the genetics lab at CHOP. Q: How did you feel when Dr. Krantz told you that he had found this genetic glitch in Letas exome?

They may find reassurance that CHOPS syndrome is a de novo condition which means that it resulted from a new mutation arising in a single egg or sperm that went on to form the affected child but is not present in the patients parents so it is unlikely to recur in any subsequent children. Because the SEC involves such a crucial process in cell biology, it has long been a focus of study, particularly in cancer, said Krantz. The goal of this research is to try to identify babies as early as possible in an effort to decrease the severity of developmental delay and decreased muscle tone as well as improve increased heart rate and poor weight gain.
