Background: Silver Russell syndrome (SRS) is a rare imprinting disorder with prenatal and postnatal growth retardation and feeding difficulties. The main molecular causes are loss of methylation of the 11p15.5 imprinting control region (H19/IGF2) and maternal uniparental disomy of chromosome 7. Prader-Willi syndrome (PWS) is a complex neurodevelopmental imprinting disorder with neonatal muscular hypotonia, failure to thrive to insatiable appetite, sho...

Background: Maternal uniparental disomy of chromosome 16 (UPD(16)mat) is defined as the presence of two homologous chromosomes 16 inherited from only the mother. To our knowledge, 49 live-born UPD(16)mat patients without chromosomal abnormalities other than that in chromosome 16 have been reported. UPD(16)mat patients presented with non-specific clinical features such as preterm birth, growth retardation, congenital heart diseases (CHDs) and hypospadias. Silver-Russell syndrom...

Background: In Silver-Russell Syndrome (SRS), it is known that puberty starts early, frequency of premature adrenarche increases and adrenarche progresses aggressively. However, data regarding gonadal functions and testicular development in males during pubertal period is still insufficient.Methods: Twenty-four cases (9F, 15M) who were followed-up with diagnosis of SRS between 1990-2020 were included in the study. The di...

Background: In a previous study, we reported that adult height (AH) outcomes in growth hormone treated males with Silver-Russell syndrome (SRS) were negatively correlated with estradiol concentrations before start of puberty and in early puberty. Whether elevated estradiol concentrations originated from adrenal or testicular androgens is unclear. We aimed to describe androgen secretion patterns and investigate correlations between androgen concentrations and A...

Background: Carbohydrate counting is an essential part of comprehensive diabetes management and is required for children and adolescents with type 1 diabetes mellitus (T1DM), according to available guidelines. However, there is no specific evidence-grading for carbohydrate counting. This review was done to determine the effectiveness of carbohydrate counting in improving glycaemic control among children and adolescents with T1DM as measured by glycated haemogl...

Background: CFAP126 gene does play a role in the regulation of pancreatic beta cell. Literature suggests that CFAP126 was significantly downregulated in human islet cells of pre-diabetic as compared to non-diabetic and further downregulated in type 2 diabetics. However, to date CFAP126 has not been reported to cause clinical diabetes. We are reporting 2 diabetic siblings, with strong family history of type 2 diabetes on maternal side...

Background: In adrenal gland 3β-HSD2 catalyses the conversion of Δ5 to Δ4 steroids (i.e., pregnenolone to progesterone,17 α-hydroxypregnenolone to 17-OHP and DHEA to androstenedione). Defect in this enzyme can affect glucocorticoid, mineralocorticoids and sex steroid synthesis but the clinical and biochemical profile can be very complicating and confusing due to conversion of intermediate steroids to more ac...

Background: Girls with Turner Syndrome (TS) are at an increased risk of primary ovarian failure. Oestrogen replacement is commenced at around the age of 12 years, in girls who do not enter puberty spontaneously, with incremental changes to the dose over the next 3 years until adult replacement doses are achieved. We have previously shown good correlation between serum and urinary LH (uLH) and FSH (uFSH) in children being assessed for disorders of puberty.<...

In adolescence, diagnosis of polycystic ovary syndrome (PCOS) is challenging because characteristics of normal puberty often overlap with signs and symptoms of PCOS. Anti-Müllerian hormone (AMH) is one of the important biomarkers suggested to confirm the diagnosis of PCOS and to manage the treatment process in adolescence. The aim of this study was to evaluate the diagnostic role of anti-müllerian hormone for PCOS in adolescent females, and to study its association t...

X-linked hypophosphataemia (XLH) is the most common form of inherited hypophosphataemic rickets, caused by loss-of-function mutations in the gene encoding phosphate-regulating endopeptidase homologue X-linked (PHEX), resulting in excess circulating fibroblast growth factor 23 (FGF-23).1,2 In children, clinical features include delayed walking, waddling gait, leg bowing, pain, spontaneous dental abscesses and growth failure. Current therapies do not treat the underly...
