Green List (high evidence)

AR Combined D-2 and L-2 hydroxyglutaric acidurea. Seizures are a feature. Muntau et al, 2000 - 3 patients including 2 sibs - all had seizures and other features. All died in early childhood - transmission patterns suggestive of AR - don't think genetic testing done. Nota et al, 2013, 12 patients from unrelated families of Arabic, European or Latin American descent - all had seizures, missense, nonsense and fs -hom/compound het in all patients. Edvardson et al, 2013 - 18 month old girl - developed epilepsy - compound het mutation. Pop et al, 2018 - overview. To date 16 mutations reported (26 patients) - 75% missense, seizures seen clinically in 20 patients - functional assay done to look at expression studies in the missense variants - variants did seem to lead to impaiment of CIC function, in addtion those with less impaired function seemed to have a milder presentation.

Green List (high evidence)

Inclusion of this as a green gene on this panel is appropriate, based on the review in the Undiagnosed metabolic disorders panel and the views of clinical expert, Dr Arianna Tucci, UCL.
