Background: The hCG stimulation test is a valuable method for assessing androgen production but there is a need to explore its utility in assessing androgen responsiveness and long-term prognosis.Objective and hypothesis: Our aim was to explore the effect of hCG stimulation on the peripheral transcriptome in boys undergoing investigation for DSD.Method: Thirteen boys undergoing investigation for 46,XY DSD received i.m. hCG 1500 U o...

Background: Being born small for gestational age (SGA) is linked with higher systolic blood pressure (SBP). Fetuses with growth restriction (FGR) may be either SGA or appropriate size for gestational age at birth. However, it is not known which factors contributing to size at birth influence the relationship with SBP.Aim: To determine whether antenatal markers of FGR can predict the upper quartile of childhood SBP.<p...

Background: Many studies have associated being born small for gestational age (SGA) [and by implication having suboptimal fetal growth (SFG)] to childhood cardiometabolic risk markers. However, not all growth-restricted pregnancies result in SGA. In the Manchester BabyGRO study, we focussed on pregnancies at risk of SFG with most babies born AGA, and using transcriptomic and metabolomic data we have identified pathways related to higher child systolic blood pr...

Background: A mutation in EIF2S3 (NM_001415; Xp22.11) was previously associated with microcephaly and developmental delay in a single pedigree. EIF2S3 encodes the eukaryotic translation initiation factor 2 subunit 3 (eIF2γ), the largest of three EIF2 subunits. EIF2 initiates protein synthesis by forming a ternary complex with GTP and initiator methionyl-tRNA which then binds to the 40S ribosomal subunit, enabling scanning of mRNA from the 5′ end to...

Introduction: The molecular aetiology of familial glucocorticoid deficiency (FGD) is very heterogeneous. A recent report of a genetic variant in TXNRD2, the gene encoding thioredoxin reductase Type 2, in a South Asian kindred with FGD suggests that the maintenance of redox balance may be critical for adrenocortical function. We present the second report of an individual from another south Asian family harbouring a different pathological variant in <em...

Introduction: Prader-Willi Syndrome (PWS), a common syndromic form of childhood obesity, is characterized by failure-to-thrive during infancy followed by progressive hyperphagia and obesity in childhood. The pathogenesis of hyperphagia and weight-gain in PWS is poorly understood and management strategies have had variable and limited success. Several studies support an etiological contribution of dysbiotic gut microbiota in the metabolic derangements of obesit...

Introduction: Among Disorders of Sex Development (DSDs), XY DSD, represents the most challenging group in terms of identifying a diagnosis.Objectives: The aim of the study was to determine the prevalence of biochemical and molecular genetic tests in a cohort of boys with XY DSD and to collate the phenotypes of patients with results of laboratory investigations and presence of associated abnormalities.Methods: New and existing cases...

Introduction and aim: Prader-Willi syndrome(PWS), is a genetic disorder caused by the absence of paternal genes located on chromosome 15q11.2-q13. In this multi-central study; patients with PWS were followed for 2 years. Initial clinical and laboratory findings, growth hormone(GH) treatments and their responses were evaluated.Patients and Methods: 54 patients from 10 pediatric endocrine centers were involved and data was...

Background: In children undergoing investigation of testicular function the relationship between serum anti-Mullerian hormone (AMH) and the testosterone response to hCG stimulation test (HST) is unclear.Method: 75 children (3F, 72M) with a median age of 1.08 years (range, 0.003, 14.3) were investigated for suspected DSD by AMH on D1 and testosterone on D1 and D4, before and after 3-day HST. Of these children, 27 had an additional prolonged HST. Normal te...

Background: Myo-inositol(MI)is a polyol involved in intracellular signaling pathways of insulin and MI has been used orally for therapeutic purposes in girls and adult women with polycystic ovary syndrome(PCOS)with variable success. As yet, serum MI levels have not been assessed in girls with PCOS.Aim: Our primary goal was to compare serum MI levels in girls with PCOS with those in healthy peers. Secondary goal was to in...
