The UK NSC recommendation on Glutaric Aciduria Type 1

Find general information about population health screening.

Why is screening recommended by UK NSC?

The UK NSC has recommended screening for Glutaric aciduria type 1 (GA1) within the current Newborn Blood Spot Screening Programme. A one year evaluation of screening in the UK found that screening for this rare inherited organic acid disorder will identify babies early and lead to treatment to help prevent serious problems developing.  

More about GA1

A baby with Glutaric Aciduria Type 1 (GA1) has problems breaking down the particular amino acids lysine and tryptophan.

In children with GA1, a minor illness, such as a chest infection or a tummy upset, can lead to serious problems and the child would require immediate hospital treatment. Early signs may be vomiting, excessive sleepiness and breathing difficulties.

Without treatment the child can go into a coma and many patients die in early adulthood. If they recover from the coma there is a high likelihood of brain damage that can affect their ability to control muscles and movements. This means that they may be unable to sit, walk, talk or swallow.
