Introduction: Recently the incidence of type 2 diabetes was explosively increased in children and adolescents. The underlying mechanism of childhood-onset type 2 diabetes mellitus may be different to the adult-onset type 2 diabetes. Therefore, it is useful to conduct genetic study in children with type 2 feature to understand underlying cause of glycemic dysregulation as well as for the management of diabetes mellitus.Case</stron...

Background: GH insensitivity is caused by disturbances of GH receptor function or inability to transduce the hormone signal. Affected children are severely growth retarded and may also present immune complications when the transducer STAT5B is defective. Only autosomal-recessive STAT5B mutations have been described to date.Clinical case: Two male 14.5 year monozygotic twins presented with heights of 131.5 cm (−5.3 SDS). Bone age of the ind...

Background: Heterozygous loss-of-function variants of fibroblast growth factor receptor 1 (FGFR1) are genetic causes of Combined Pituitary Hormone Deficiency (CPHD), Kallmann syndrome (KS) with anosmia/iposmia, Congenital Hypogonadotropic Hypogonadism (CHH) with normosmia and Septo-Optic Dysplasia. It is well-known that these variants are the main genetic factor underlying the development of CHH and KS; however, they have only occasionally been identified in C...

Objective: Central precocious puberty (CPP) is a common condition in pediatric endocrinology practice. Gonadotropin-releasing hormone agonists (GnRHa) treatment is safe, but the real effect on final height and the ideal timing for treatment remains controversial. The purpose of the authors was to evaluate a nationwide representative group of CPP Portuguese girls treated with GnRHa, assess the effectiveness of treatment and the growth outcome before and after 8...

Background: Idiopathic central precocious puberty (CPP) is mostly described as an isolated entity. A few studies have shown its association with clinical syndromes and rare cases of chromosomal abnormalities.Objective: To clinically characterize patients with CPP, pointing out prevalent associated conditions and phenotypes.Patients and Methods: One hundred and forty-five patients with idiopathic CPP were retrospectively evaluated. ...

Introduction: Central Precocious Puberty (CPP) results from the premature activation of the hypothalamic-pituitary-gonadal axis. Is defined by the onset of secondary sexual characters before 8-years-old in girls and 9-years-old in boys. It’s associated with accelerated growth and advanced bone maturation and can lead to early epiphyseal fusion and reduced final height at adult age.Aims: To evaluate and compare the ...

Introduction: Since the 1980s, long-acting gonadotropin-releasing hormone analogues (GnRHa) have been the standard treatment for central precocious puberty (CPP).Aims: To evaluate the short-term response (at 6 and 12 months) of treatment with GnRHa in female children diagnosed with CPP, regarding growth, bone maturation (Greulich and Pyle method), predicted adult height (PAH) and pubertal development (Tanner stages)....

Objective: To determine the mutation in the SRY gene in a 46,XY complete gonadal dysgenesis patient with bilateral gonadoblastoma and coexisting dysgerminoma. Evaluate the functional consequence of mutated SRY gene in the tumor risk of 46,XY DSD.Methods and Materials: The proband was a 13-year-old girl who was admitted for examination due to undeveloped secondary sexual characteristics. She had no breas...

Background: Neonatal diabetes (ND) is a rare monogenic form of diabetes presenting within the first six months of life. The most frequent causes include mutations in KCNJ11, ABCC8 and insulin genes, but up to 40% of patients remain without a molecular genetic diagnosis.Case presentation: Case 1: a female newborn of non-consanguineous parents, born at 35 weeks, SGA. She presented with hyperglycemia at second day of life...

Oculocerebrorenal syndrome of Lowe (OCRL) is an X-linked and multisystem disorder with clinical symptoms of congenital cataracts, severe mental retardation, hypotonia, areflexia, and incomplete Fanconi syndrome of the proximal renal tubules. We report a 15-year-old short stature male with a severe form of OCRL syndrome, diagnosed based on bilateral congenital cataract, proteinuria, tubulopathy, and dysmorphic findings. The physical examination revealed a height of 152 cm (-2.7...
