  • Glutaric Aciduria 1 (GA 1), also known as Glutaric Acidaemia 1 and Glutaryl CoADehydrogenase Deficiency is a rare autosomal recessive inborn error of metabolism caused by deficient activity of the enzyme glutaryl-CoA dehydrogenase.
  • It presents with acute encephalopathy in young children, usually under the age of two years.
  • Some individuals have presented with subdural and retinal haemorrhages without a history of trauma and case reports have highlighted the similarity of these findings to those seen in non-accidental injury.
  • We aim to estimate the incidence of GA 1 in children in the UK and Ireland and describe its distribution by age and ethnic group as well as look at symptoms and signs at presentation including the presence or absence of subdural and retinal haemorrhage.
  • A follow up questionnaire will be sent at one year to explore short term morbidity and mortality of these children after diagnosis.        

Duration: July 2010 – July 2012 inclusive
