In the Amish community, where GA1 is overrepresented Morton,patients with GA1 did not and still don’t receive tryptophan-free formulas, gluyarica as the sole source of amino acids, nor as a supplement to protein restriction. All 12 previously reported patients had a homogeneous phenotype presenting in infancy with debilitating dystonia and choreoathetosis.

In patients suspected of having the disorder, repeated examinations of organic acids in the urine and enzyme assay may be necessary to confirm the diagnosis. The pregnancy was terminated, and postmortem studies confirmed the diagnosis of glutaric acidemia.

However, this does not significantly change blood concentrations of glutarylcarnitine or esterified carnitine, [4] suggesting that oral supplementation is suboptimal in raising tissue levels of carnitine.
