چکیده

Background and objectiveMethylmalonic acidemia (MMA) propionic (PA) are inborn errors of metabolism. While survival MMA PA patients has improved in recent decades, long-term outcome is still unsatisfactory. A protein restricted diet the mainstay for treatment. Additional amino acid mixtures (AAM) can be prescribed if natural insufficient. It unknown dietary treatment have an impact on outcome.DesignWe performed a nationwide retrospective cohort study evaluated both longitudinal clinical course Dutch patients.

Optic neuropathy in methylmalonic acidemia and propionic acidemia.

BACKGROUND Methylmalonic acidemia (MMA) and propionic acidemia (PA) are rare hereditary disorders of protein metabolism, manifesting early in life with ketoacidosis and encephalopathy and often resulting in chronic complications. Optic neuropathy (ON) has been increasingly recognised in both conditions, mostly through isolated case reports or small cases series. We here report the clinical feat...
