چکیده
Hajdu-Cheney syndrome (HCS) and serpentine fibula-polycystic kidney syndrome (SFPKS) share many similarities, including craniofacial abnormalities, bony deformities, and renal involvement. Because mutations in exon 34 of NOTCH2 have been identified recently in both HCS and SFPKS patients, it has been suggested that these two syndromes be classed as the same disorder. A 3-year-old boy presented with polycystic kidneys and club feet detected during the fetal period; however, acroosteolysis and curved fibulae were not observed. His mother showed osteoporosis and had a history of compression fractures in the spine without renal anomalies. Although the same novel mutation in NOTCH2 was found in both the mother and her son, these patients displayed different clinical manifestations. In this report, we present a familial case of HCS in a boy and his mother that was suspected on physical examination and radiological findings. We speculate that HCS and SFPKS are a single disease entity with a wide spectrum of clinical manifestations associated with truncating mutations in exon 34 of NOTCH2.

A 21-year-old man with diabetic ketoacidosis (DKA) displayed short and clubbed fingers and marked eyebrow, which are typical of Hajdu-Cheney Syndrome (HCS). Laboratory findings confirmed type 1 diabetes mellitus (DM). After conservative care with hydration and insulin supply, metabolic impairment was improved. Examinations of bone and metabolism revealed osteoporosis and craniofacial abnormalit...

Hajdu Cheney Syndrome (HCS), Orpha 955, is a rare disease characterized by acroosteolysis, severe osteoporosis, short stature, specific craniofacial features, wormian bones, neurological symptoms, cardiovascular defects and polycystic kidneys. HCS is rare and is inherited as autosomal dominant although many sporadic cases have been reported. HCS is associated with mutations in exon 34 of NOTCH2...

Identification of a Novel Mutation in CNNM4 Gene in an Iranian Family with Jalili Syndrome
Background and Objectives: Jalili syndrome is a rare autosomal recessive genetic disorder, which so far, only 33 families with this disorder have been reported worldwide. Patients with this disease simultaneously develop cone-rod retinal dystrophy (CRD) and amelogenesis imperfecta (AI). In this study, a mutation causing Jalili syndrome, was investigated in an Iranian family. Case Report: The...
متن کاملIdentification of a Novel CLCNKB Mutation in an Iranian Family with Bartter Syndrome Type 3.
Bartter syndrome (BS) is a group of uncommon genetic disorders of reabsorption of salt in the cortical thick ascending limb (TAL) of the Henle's loop, typically distinguished by metabolic alkalosis, salt loss, hypokalemia, hyperreninemic hyperaldosteronism and normal blood pressure. Bartter syndrome type 3, recognized as a classic BS (CBS), occurs because of mutations in CLCNKB gene. We enroll...
