Mutation of SHOC2 promotes aberrant protein N-myristoylation and causes Noonan-like syndrome with loose anagen hair

Marco Tartaglia and colleagues report the identification of mutations of SHOC2 in individuals with Noonan-like syndrome with loose anagen hair. The mutations cause aberrantly acquired N-myristoylation of SHOC2 resulting in aberrant targeting of SHOC2 to the plasma membrane. SHOC2 is believed to function as a scaffold linking RAS to downstream signal transducers.
