Abstract :

We previously identified the genetic basis of a previously unrecognized X-linked, infantile lethal Mendelian disorder. This is the first human genetic disorder identified that results from a hypomorphic allele in the N-terminal acetylation pathway, with Nt-acetylation being one of the most common protein modifications in humans. The functional implications of Nt-acetylation for the thousands of proteins that are modified by it remain quite elusive, although recent data suggest a role as a destabilization signal for proteins and involvement in the secretory pathway. To begin our long-term study of this disease, we are utilizing several different cellular model systems and model organisms. We are also performing X-inactivation studies in the female carriers, along with further characterizing the pathophysiology and phenotype of this disease. I will present some results in regards to this understudied protein modification, now for the first time implicated in a human disease.
