Genes affected

NAE1 (HGNC:621): (NEDD8 activating enzyme E1 subunit 1) The protein encoded by this gene binds to the beta-amyloid precursor protein. Beta-amyloid precursor protein is a cell surface protein with signal-transducing properties, and it is thought to play a role in the pathogenesis of Alzheimer's disease. In addition, the encoded protein can form a heterodimer with UBE1C and bind and activate NEDD8, a ubiquitin-like protein. This protein is required for cell cycle progression through the S/M checkpoint. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

NAE1 Gene-Disease associations (from GenCC):

• neurodevelopmental disorder with dysmorphic facies and ischiopubic hypoplasia
