Shashi-Pena Syndrome is an ultra-rare neurodevelopmental disorder caused by a change, or mutation, in the ASXL2 gene. There are an estimated 40-45 individuals diagnosed with Shashi-Pena Syndrome globally. Common features of Shashi-Pena Syndrome include distinct facial features (large head, wide-set eyes, birthmarks), low muscle tone (hypotonia) developmental delay, difficulty controlling blood sugar, orthopedic complications (bone density, advanced bone age, scoliosis), heart defects, behavioral and sensory challenges, constipation, and seizures. There are no treatments to address the underlying cause of Shashi-Pena Syndrome. Treatment includes managing individual symptoms.
