Hajdu-Cheney syndrome is an autosomal dominant disorder characterized by acroosteolysis of the distal phalanges associated with digit abnormalities, distinctive craniofacial changes, dental anomalies, and a proportionate short stature. The pubertal development of children with Hajdu-Cheney syndrome is usually normal in the literature, although we here first describe a girl who was found to have Hajdu-Cheney syndrome accompanied with premature ovarian failure. She showed a follicle-stimulating hormone-dominant response on luteinizing hormone-releasing hormone test and did not show any sex differentiation abnormality or adrenal steroid hormone deficiency. On the basis of the findings in our patient, premature ovarian failure may be a complication of Hajdu-Cheney syndrome and thus an early endocrinological evaluation of patients is important.

Hajdu-Cheney syndrome (HCS), caused by a heterozygous gain of function variant of the NOTCH2 gene, is a rare skeletal dysplasia. Although the main presentation is acro-osteolysis, osteoporosis, and facial dysmorphism, having a wide range of clinical manifestations creates diagnostic difficulties. Here, a 15-year-old male patient with HCS who had no complaints until this age except for two short bone fractures and one vertebral collapse fracture due to a fall was reported.

Background: Notch signaling, a conserved mechanism of cell-to-cell communication, plays a crucial role in regulating cellular processes such as proliferation and differentiation in a context-dependent manner. However, the specific contribution of Notch signaling to the progression of polycystic kidney disease (PKD) remains unclear.
Methods: We investigated the changes in Notch signaling activity (Notch1-4) in the kidneys of autosomal dominant PKD (ADPKD) patients and two ADPKD mouse models (early and late onset).

Hajdu Cheney Syndrome (HCS), a monogenic disorder associated with NOTCH2 pathogenic variants, presents with neurological, craniofacial and skeletal abnormalities. Mouse models of the disease exhibit osteopenia. To determine the consequences of a HCS pathogenic variant in human cells, induced pluripotent NCRM1 and NCRM5 stem (iPS) cells harboring a NOTCH2 mutation or null for HES1 alleles were created.
