Abstract excerpt
We reevaluated a previously reported family with an X-linked mental retardation syndrome and attempted to identify the underlying genetic defect. Screening of candidate genes in a 10-Mb region on Xq25 implicated CUL4B as the causative gene. CUL4B encodes a scaffold protein that organizes a cullin-RING (really interesting new gene) ubiquitin ligase (E3) complex in ubiquitylation. A base substitution, c.1564C-->T,...
