I don't know

Comment on list classification: changed from amber to green due to gene symbol update, green rated PROSC is previous symbol for PLPBP

HGNC update complete. PROSC removed from panel, HGNC approved gene symbol PLPBP remains
Created: 7 Nov 2017, 12:08 p.m.
Comment on list classification: delete- although PLPBP is the current approved HGNC gene symbol, the previous symbol PROSC is in our current (Out of date) HGNC version so the ENSG ID can be found and used in Pipeline. PROSC is on this panel with the same review (now Green rated), and that entry is the one that will be updated to the approved gene symbol of PLPBP when panelapp moves to the new version (6th Nov 2017)

Previous gene symbol PROSC. Pyridoxal phosphate-responsive epilepsy (PNPO associated) is rare form of autosomal recessive neonatal epileptic encephalopathy. Darin (2016) PMID:27912044: Of the five individuals with PROSC mutations all affected infants presented with seizures on day 1 of life, apart from subject 7, who presented at 1 month of age. Clinical characteristics of all five individuals all were noted as showing learning difficulties in addition to three with motor delay and four with speech delay.

Panel promoted to version 2.0

Ellen McDonagh (Genomics England Curator)

12.03.2018: Due to major updates completed (Phase 1, 2 and 3), this panel was promoted to Version 2 in order to reflect the major updates since November 2017 which have resulted in reviews for 836 genes added by Genomics England Curators and the Clinical Team, 130 new Green genes added to the interpretation pipeline (from 751 to 881 Green genes), and the gene total has increased from 1879 to 1927.
