Sarah Leigh (Genomics England Curator)

Associated with phenotype in OMIM and as a confirmed G2P. At least 11 variants reported of which two are large deletions (46kb and 3.9kb)(PMIDs 17152059;16566017).
Created: 4 Jan 2018, 10:48 a.m.
Comment on phenotypes: Gene2Phenotype confirmed gene with ID related disease – Lacticacidemia due to PDX1 deficiency
Created: 4 Jan 2018, 10:44 a.m.

Helen Brittain (Genomics England Curator)

Comment when marking as ready: Although the majority present with lactic acidosis / seizures in infancy, approximately 25% in one series (25087164) presented with delayed psychomotor development. On balance, seems appropriate for inclusion.

Louise Daugherty (Genomics England Curator)

Comment on list classification: Changed rating of gene from Amber to Green. This gene was rated as Green in v2.467 and incorrectly automatically demoted to Amber in v2.468. This was due to a defect in the automatic PanelApp uploading tool where a reference gene list was added as a new Source (Victorian Clinical Genetics Services), and under certain conditions associated to previous sources listed, resulted in the rating of the gene being automatically changed when it should not have been.
Created: 29 Sep 2018, 7:10 p.m.
Comment on list classification: This gene is from an expert list and needs further assessment by the Genomics England curation team to assess inclusion and pertinence to this panel.
