CHOPS syndrome

Title

Summary Summary

CHOPS syndrome is rare condition that affects many different parts of the body. "CHOPS" is an acronym for the primary signs and symptoms associated with the condition, including cognitive impairment, coarse facial features, heart defects, obesity, pulmonary (lung) problems, short stature, and skeletal abnormalities. CHOPS syndrome is caused by changes (mutations) in the AFF4 gene and is inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person.^[1]
