Follow-up of patients with short-chain acyl-CoA dehydrogenase and isobutyryl-CoA dehydrogenase deficiencies identified through newborn screening: One centers experience

Purpose: To evaluate the growth, development, and medical histories of children with short-chain acyl-CoA dehydrogenase and isobutyryl-CoA dehydrogenase deficiencies identified through newborn screening. Methods: Chart review of patients diagnosed with short-chain acyl-CoA dehydrogenase or isobutyryl-CoA dehydrogenase deficiency at our center. Results: There were 16 children with short-chain acyl-CoA dehydrogenase deficiency, including 10 with two pathogenic mutations, and 8 with isobutyryl-CoA dehydrogenase deficiency. All but one patient has had normal growth and development, and that patient also had the 22q deletion syndrome. Conclusion: Our data and previous reports suggest that the majority of individuals with short-chain acyl-CoA dehydrogenase or isobutyryl-CoA dehydrogenase deficiencies have normal growth and development.
