摘要: We used an exome-sequencing strategy and identified allelic series of NOTCH2 mutations in Hajdu-Cheney syndrome, autosomal dominant multisystem disorder characterized by severe progressive bone loss. The syndrome are predicted to lead the premature truncation with either disruption or loss C-terminal proline-glutamate-serine-threonine-rich proteolytic recognition sequence, absence which has previously been shown increase Notch signaling.
