Background: Mandibular hypoplasia, deafness, progeroid features, and lipodystrophy (MDPL) syndrome is a genetic disorder which was first recognized in 2010. MDPL syndrome is comprised of mandibular hypoplasia, deafness, progeroid features, lipodystrophy, hypogonadism and metabolic disorders. It is caused by an autosomal dominant mutation in the polymerase delta 1 (POLD1) gene, with <30 genetically confirmed cases to date.Cas...

Background: Familial hCG syndrome is a rare and benign cause of elevated serum beta human chorionic gonadotropin (β- hCG), moreover, elevated β-hCG in cerebrospinal fluid(CSF) has never been reported in familial hCG syndrome.Object: To report the two Chinese families of familial hCG syndrome with elevated β-hCG concurrently in blood/CSF.Method: We described the clini...

Objective: To summarize the metabolic status in children with classic congenital adrenal hyperplasia(CAH) due to 21-hydroxylase deficiency (21OHD).Methods: Children with classic 21OHD from Pediatric Endocrinology Clinics at the First affiliated hospital of Sun Yat-Sen University from January 1990 to February 2023 were included in the study. The prevalence of overweight/obesity, dyslipidemia [high triglyceride (TG), high ...

Introduction: Abdominal subcutaneous adipose tissue (SAT) is subdivided into two depots by the fascia of Scarpa. The deep SAT (dSAT) and superficial SAT (sSAT) are morphologically and metabolically distinct, with dSAT reportedly being more similar to visceral adipose tissue (VAT) in terms of elevating the risk for obesity-related complications. Conversely, sSAT appears to be more similar to lower-body SAT. The relationship between dSAT and metabolic disease ha...

Resistance to thyroid hormone due to mutations inactivating thyroid hormone receptor-Beta occurs in one in 40,000 individuals and can arise de novo or be inherited, generally in a dominant fashion. Clinical manifestations are widely variable and include failure to thrive in infancy. The biochemical diagnosis is usually straightforward: high serum fT4 and non-suppressed TSH.We report two brothers who both inherited the known c.728G>A, p.R24...

Stüve-Wiedemann syndrome (SWS) is an autosomal recessive disorder characterized by bowing of the long bones and other skeletal anomalies, neuromuscular abnormalities, dysautonomic symptoms, and respiratory and feeding distress usually resulting in early death.We report a girl, aged 6 years, with SWS. We measured bone mineral density in the lumbar spine, using dual-energy x-ray absorptiometry (DXA) with a densitometer (Hologic). The result is express...

Introduction: Vitamin D resistant rickets type II (VDDR-II) is a disease with a difficult treatment developed as a result of mutations in VDR gene. Despite high dose active vitamin D and oral calcium treatments, sufficient recovery cannot be achieved mostly. Successful results with intravenous calcium infusion that is an alternative treatment have been reported; however, serious restrictions and complications such as hospitalization, catheter infection, thrombosis, skin necros...

Introduction: The carbonic anhydrase II (CA II) deficiency syndrome is a rare autosomal recessive disorder associated with osteopetrosis, renal tubular acidosis (RTA), and cerebral calcification (CADS; autosomal recessive osteopetrosis type 3). Other features include visual and auditory impairment, short stature, a large cranial vault, history of multiple skeletal fractures, developmental delay and cognitive defects, anemia, splenomegaly and secondary erythropoiesis. We report...

Introduction: Ellis Van Creveld syndrome (EVC) is a rare condition which is characterized with disproportionate short stature, postaxial polydactyly, and dysplastic nails and teeth. It is a rare autosomal recessive disorder due to mutations of EVC 1 and 2 genes located on chromosome 4p16. EVC syndrome is a chondroectodermal dysplasia. Congenital heart defects; especially atrial septal defect and single atrium occurs in 60% of affected individuals. Here we report a 5 year-old f...

Pseudohypoparathyroidism (PHP) is a disease of rare frequency. There are five subtypes with each having different phenotypes and blood laboratory test results, which depend on gene mutation and hereditary styles. Among them, the most common type is PHP Ia which inherits maternal gene mutation and expresses Albright’s hereditary osteodystrophy (AHO) appearance, hypocalcemia, hyperphosphatemia and serum parathyroid hormone elevation. Another type, pseudo-pseudohypoparathyro...
