5 unrelated families with homozygous mutations in SVBP. Some shared the same founder variant, p.Q28*. The mutations segregated with the disorder in all families. In vitro functional cellular expression studies showed that protein levels of the SVBP mutants were barely detectable, suggesting instability, and that the mutant proteins had lost VASH/SVBP catalytic detyrosination activity toward tubulin. Knockdown of about 50% Svbp expression using shRNA in rat hippocampal neurons impaired the formation of excitatory synapses compared to controls.
