Background: Cardiometabolic (CM) risk is linked to being small for gestational age (SGA, birthweight <-2SDS). Fetal growth restriction (FGR) may not result in SGA. We focused on potential CM risk in children born following pregnancies at higher risk for FGR.Aims: To identify associations between fetal and childhood weight trajectory quartiles and CM risk markers. 2.To define molecular pathways potentially associated w...

Introduction: Thyroid surgery in children is associated with high risk of recurrent laryngeal nerves (RLN) damage. It is due to complex and variable anatomy, high bleeding which decreasing visualization and requiring instrumental hemostasis. Large goiters change of syntopy, metastatic process requires bigger aggression and volume of intervention. The risk of damage significantly increases during repeated operations due to the scar process. There is significant...

Background: Hypospadias is a common characteristic of Disorders of Sex Development (DSD). At the present time a molecular diagnosis is not reached in over 50% of cases. The DDD Study represents a useful resource of large molecular and phenotypic datasets obtained from individuals with an undiagnosed developmental abnormality including DSD.Objective: To review associated features and identify likely pathogenic variants in previously undiagnosed DDD partic...

Background: Collaborative project to review the phenotypic and genotypic data from children recruited to the UK wide deciphering developmental disorders (DDD) study.Objective and hypotheses: To report the frequency and range of disorders of sex development (DSD) phenotypes observed in DDD participants who have one or more associated ‘neurodevelopmental delay’ diagnostic human phenotype ontology (HPO) term.Method: Retrospe...

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...

Hypophosphatasia (HPP), an inborn-error-of-metabolism, has broad-ranging severity caused by inactivating mutation(s) in the gene for tissue non-specific alkaline phosphatase (TNSALP). HPP in children features premature loss of deciduous teeth often with impaired skeletal mineralization, poor growth, static myopathy, and compromised physical function. To date there are no approved treatments for HPP. Perinatal and infantile forms have very high morbidity and mortality and the j...

Background: An activation cascade of specific genes sets up the initiation of sex determination leading in males to testes formation and synthesis of testicular hormones. Disruption of this gene cascade may cause a spectrum of disorders/differences of sex development (DSD) phenotypes. Here we describe for the first time two sisters suffering from 46,XY DSD, who by whole exome sequencing were shown to carry a mutation in the X-linked StAR-related lipid transfer...

Background: There is little information on growth and fractures in boys with Duchenne Muscular Dystrophy (DMD).Objective & hypotheses: To determine the extent of growth & skeletal morbidity in a contemporary cohort of DMD in the UK.Method: Clinical details of 832 boys with DMD in the North Star database (2006–2015) from 23 centres were analysed following categorisation into five age groups: A:<5 years (n, ...
