Background: Achondroplasia (ACH), the most common short-limbed skeletal dysplasia, is characterized by impaired endochondral ossification resulting from gain-of-function pathogenic variants in the fibroblast growth factor receptor 3 (FGFR3) gene, a negative regulator of endochondral bone growth. People with ACH are at risk for several significant co-morbidities, including brainstem compression due to foramen magnum stenosis, sleep-disordered breathing, chronic...

Background: Conventionally, 46 XX infants with congenital adrenal hyperplasia (CAH) were reared as females, even if considerably virilised at birth. However, lately there has been some debate on this stance, and male gender of rearing is also being considered.Objective and hypotheses: We report on a 9 year old genetically female child (N) with salt wasting CAH reared as a male, with precocious female puberty, currently suppressed with GnRH analogs, and d...

Growth hormone deficiency (GHD) is a relatively rare cause for short stature resulting from insufficient secretion of growth hormone (GH). With complicated etiology, GHD can coexist in numerous syndromes or disorders such as Turner Syndrome. So, it is necessary to take genetic analysis to patients with GHD especially those perform various phenotypes. A 9.5 years old boy complained of short stature was diagnosed with GHD by height velocity (HV) <5 cm/year, delayed bone age ...

Introduction: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires appropriate diagnosis and treatment. The most common cause of PAI is congenital adrenal hyperplasia (CAH), but other well-established aetiologies include metabolic and autoimmune disorders, and physical damage. Mutations in more than 30 genes have now been associated with PAI, with considerable biochemical and phenotypic overlap. It is therefore importan...

Pregnancy associated plasma protein (PAPP)-A2 is an insulin-like growth factor (IGF) binding protein (BP) protease that regulates IGF-1 availability affecting postnatal growth. Mutations in human PAPP-A2 cause short stature and changes in bone size and mineral density. The present study aimed to characterize the effects of constitutive Pappa2 gene deletion on hypothalamic regulation of energy homeostasis in adult male and female mice. In addition to being sho...

Objectives: The etiopathogenetic of childhood obesity is related to genetic and environmental factors: not only caloric intake or physical activity have an important influence, but also circadian rhythms, including healthy sleep.The objectives of this study were: a) to analyze the different patterns and duration of sleep, eating habits, meal schedules, time dedicated to exercise and screens of obesity children; b) to evaluate its possibl...

Background: Between the 6000 monogenic disorders, only few are due to a single mutation. Recently, a specific mutation has been described in TUBB3, encoding tubulin beta 3, in the association of Moebius syndrome (MS) and Kallmann syndrome (KS). MS is a congenital paralysis of eye and face’s muscles and can be caused by mutations of TUBB3. KS combines hypogonadotropic hypogonadism and anosmia.Objective and hypotheses: The combination of these two syn...

Background: Hypoglycemia etiology in children is heterogeneous and varies by age. Both growth hormone (GH) and cortisol deficiencies may present with hypoglycemia; the latter may result in an adrenal crisis that may be fatal.Objectives: To evaluate responses of cortisol and GH to spontaneous hypoglycemia in infants and children, and to assess the rate of true cortisol deficiency in children, defined as cortisol<500 nm...

Background: Congenital GH deficiency (GHD) can be isolated (IGHD) or combined with other pituitary hormone deficiencies (CPHD). The identification of mutations has clinical implications for the management of patients and genetic counseling1.Objective: To prospectively conduct a molecular-genetic analysis in genes associated with IGHD or CPHD.Method: Forty patients with IGHD (n=8) or CPHD (n=32) were stu...

Introduction: 46, XY DSD leave lifelong implications on parents and patients. Documented scientific literature on children with 46, XY DSD is scares in Sri Lanka. This study assesses the psychosocial wellbeing of parents and the quality of life in children with 46 XY DSD.Objective: To assess the psychosocial wellbeing of parents and the quality of life in children with 46, XY DSD attending the endocrine clinics at Lady R...
