      WHAT IS SERINE DEFICIENCY? Serine deficiencies are a series of inborn metabolic errors that affect the synthesis of this amino acid. These errors cause a deficiency in the amino acid which mainly affects the nervous system. WHAT IS SERINE? Serine is an amino acid, a simple molecule that is part of proteins. However serine is not essential in the

      Aromatic L-amino acid decarboxylase deficiency (AADCD) is a rare, autosomal recessive neurometabolic disorder that leads to a severe combined deficiency of serotonin, dopamine, norepinephrine and epinephrine. Onset is early in life, and key clinical symptoms are hypotonia, movement disorders (oculogyric crisis, dystonia, and hypokinesia),

      Neurotransmitters are built in the body from amino acids with the assistance of vitamins and minerals known as “cofactors”. If the body does not take in enough of the amino acids, vitamins, or minerals to build neurotransmitters, a neurotransmitter deficiency state develops. Over time this leads to the development of diseases

      Hyperphenylalanemia is an amino acid disorder caused by decreased activity, impaired synthesis or recycling of phenylalanine hydroxylase or its cofactor, BH 4. Phenylketonuria (PKU) is caused by deficiency of phenylalanine hydroxylase. Without this enzyme, the body is unable to convert phenylalanine (PHE) into tyrosine (TYR).
