Ellen McDonagh (Genomics England Curator)

Comment on list classification: Promoted from Red to Green due to expert review from representation of the GMS Metabolic disease specialist test group; multiple cases reported and this is a treatable.
Created: 4 Dec 2019, 4:31 p.m. | Last Modified: 4 Dec 2019, 4:31 p.m.
Panel Version: 1.420
Added the 'treatable' tag due to PMID: 25653144 which reports improvement in the patient after tretment with vitamin B6.

Saikat Santra (Birmingham Children's Hospital)

Green List (high evidence)

Human variants have been reported in print and also in abstracts at SSIEM conferences 2016 and 2018. Unpublished cases also exist and it is now a recognized cause of elevated branched chain amino acid levels which may be investigated by this panel.
