Background: SHOX encodes a transcription factor implicated in skeletal development. Approximately 70% and ~2.5% of Leri-Weill dyschondrosteosis (LWD) and idiopathic short stature (ISS) patients, respectively, have a defect in SHOX or its regulatory regions.Objective and hypotheses: i) To perform SHOX mutation screening in a cohort of 585 patients referred with a clinical suspicion of LWD or ISS. ii) To determine which is the <e...

Background: Central precocious puberty is due to premature activation of the hypothalamo–pituitary–ovarian axis. In girls it is idiopathic in up to 95%. Children with clinical rapid progression are treated with prolonged activity GnRH agonist.Objective and hypotheses: Characterise cases of idiopathic central precocious puberty (ICPP) followed at our hospital comparing the group treated with GnRH agonist (group A) with the group not treated (gro...

Background: 16p11.2 microdeletion is most common chromosomal anomaly associated with syndromic obesity. The presence of a large number of flanking segmental duplications/low-copy repeat sequences with a high degree of sequence identity in the short arm of chromosome 16 (16p) leads to recurrent deletions and duplications as a consequence of non-allelic homologous recombination. A recurrent 600kb microdeletion is one of the most frequent genomic imbalances in 16...

Introduction: Individuals with ovotesticular disorders of sexual development (OT-DSD) have both seminiferous tubules and ovarian follicles. The combination of gonads could be separated (ovary-testis), unilateral (ovotestis-ovary or ovotestis-testis), or bilateral (ovotestis-ovotestis). The last one is the rarest variant (24.5%). In 60% of cases, the karyotype is 46, XX.Case Report: 15-year-old, monochorionic-monoamniotic...

2 siblings were referred for evaluation fo short stature and failure to thrive. Both were born of 3rd degree consanguinity, first and second in birth order. the first sibling was 2 1/2 year old at time of referral and had birthweight of 3.1 kg and had gross motor delay. Present height was 65 cm (SDS −6.2 S.D.)and weight was 6 kg (<3rd centile) Second sibling was 1.5 years old, with gross motor delay with height of 57 cm (SDS −6.5 S.D.</sma...

Background: Androgens are steroid hormones necessary for human sex development. Testosterone (T) and the more potent dihydrotestosterone (DHT) are maybe the best known androgens, which exert their effect by binding and activating the androgen receptor. Steroid reductases 5α (SRD5As) catalyse the conversion of T to DHT in the classic androgen production pathway, or from 17-hydroxyprogesterone to 17OH-dihydroprogesterone, and androstenedione to androstanedione in alternate ...

Background: Hypophosphatemic rickets (HR) are rare, inheritable disorders caused by excessive renal phosphate wasting. Despite a generalized mineralization defect, patients with HR are reported with a lower risk of fracture.Objective and hypotheses: The aim of this study was to evaluate the effect of bone -geometry, -microarchitecture and volumetric BMD (vBMD) on the estimated bone strength in adult patients with HR using high-resolution peripheral quant...

Introduction: Turner syndrome (TS) is a common genetic disorders with an estimated range of occuring in 25–210 per 100 000 liveborn females. In Denmark the prevalence of TS has been found to be 40 per 100 000 liveborn females. Our aim was to study the epidemiology of TS in Iceland for the period of 1968–2012.Methods: Primary source of data were hospital records and records from all pediatric endocrinologists in Iceland. To validate the data the...

Background: Hypoglycaemia precipitated by factitious insulin administration presents in a very similar way to hypoglycaemia caused by hyperinsulinism. It is difficult to ascertain clinically if the hypoglycaemia is secondary to exogenous administration or endogenous insulin secretion. Diagnosis is based on circumstantial evidence and biochemical tests which include insulin and C-peptide level.Objective and hypotheses: We would like to report a case of a ...

Background: 14½ year old girl presented with increased skin pigmentation, weakness of limbs and walking difficulty and delayed puberty.Objective and hypotheses: To evaluate the girl for the aetiology of hyperpigmentation, neuromuscular weakness and delayed development of secondary sexual characters.Method: The girl was evaluated by neurologist and found to have development delay, sensory and motor neuropathy, ataxia, amyotroph...
