Individuals with Hajdu-Cheney syndrome (HCS) present with osteoporosis, and HCS is associated with <i>NOTCH2</i> mutations causing deletions of the proline-, glutamic acid-, serine-, and threonine-rich (PEST) domain that are predicted to enhance NOTCH2 stability and cause gain-of-function.

Here, to determine the individual contributions of osteoclasts and osteoblasts to HCS osteopenia, we created a conditional-by-inversion (<i>Notch2<sup>COIN</sup></i> ) model in which Cre recombination generates a <i>Notch2</i><sup>Δ<i>PEST</i></sup> allele expressing a Notch2 mutant lacking the PEST domain.

Notch2 is a determinant of B-cell allocation in the marginal zone of the spleen and "somatic" mutations analogous to those found in HCS are associated with B-cell lymphomas of the marginal zone, but there are no reports of lymphomas associated with HCS.
