Infantile Neuroaxonal Dystrophy
Infantile neuroaxonal dystrophy (INAD) is a rare genetic disorder that affects the nervous system. It is caused by a mutation in the PLA2G6 gene which leads to the abnormal accumulation of fatty substances in nerve cells known as neuroaxonal dystrophy. Symptoms usually begin in early infancy and include delayed motor development, abnormal muscle tone and stiffness, vision problems, seizures, and cognitive impairment. As the disease progresses, it can cause difficulty with walking, speaking, and swallowing. There is currently no cure for INAD and treatment options are limited to managing symptoms. Supportive care such as physical therapy and speech therapy can help improve quality of life. Genetic counseling is recommended for families affected by INAD as it is an inherited condition. Early diagnosis and intervention are crucial in managing the symptoms of INAD and improving outcomes for affected individuals.
