hypotonia; difficulty coordinating movements (ataxia); and/or seizures. Some affected individuals may also have decreased reflexes (hyporeflexia); nystagmus; hyperactivity; and/or behavioral problems. SSADH deficiency is caused by mutations in the ALDH5A1 gene and is inherited in an autosomal recessive manner. Management is generally symptomatic and typically focuses on treating seizures and neurobehavioral issues.Succinic semialdehyde dehydrogenase (SSADH) deficiency is disorder that can cause a variety of neurological and neuromuscular problems. The signs and symptoms can be extremely variable among affected individuals and may include mild to severe intellectual disability; developmental delay (especially involving speech);
