Ellen McDonagh (Genomics England Curator)

PMID: 24847004 - a terminating variant in this gene was identified in a boy who presented in early infancy with a severe encephalopathy, developmental delay, movement abnormalities, and lactic acidosis. NAD kinase is crucial NADP biosynthesis evidenced by decreased mitochondrial NADP(H) levels in patient fibroblasts > DECR and the first step in lysine degradation are performed by NADP-dependent oxidoreductases explaining their in vivo deficiency. The authors conclude that DECR deficiency with hyperlysinemia is caused by mitochondrial NADP(H) deficiency due to a mutation in NADK2.

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.
