Ellen McDonagh (Genomics England Curator)

Please note that phenotypes that already existed for this gene panel (viewed under Gene Summary) and Ensembl transcripts were accidently uploaded under Peter Clayton (UCL Institute of Child Health)'s review and were not suggested by him. We are working on a fix in PanelApp to correct this.

Mild hyperammonaemia can be present in MSUD but the high leucine is the cause of encephalopathy
