Severe osteoporosis and mutation in NOTCH2 gene in a woman with Hajdu-Cheney syndrome.

Abstract excerpt

Hajdu-Cheney syndrome (HCS) is a rare genetic disorder characterised by acro-osteolysis, skull deformation and generalised osteoporosis. Recently, truncating mutations in the last exon of NOTCH2, a protein-coding gene, were found to be responsible. We present the case of a young woman with HCS in whom clinical and radiologic diagnosis was confirmed with DNA tests.
