Background: Registries are of key importance for a centre of expertise. Endo-ERN consists of 71 reference centres (RCs) that cover several groups of rare endocrine conditions within 8 themes (www.endo-ern.eu). It is unclear if awareness, participation and availability of registries is uniform for all conditions within Endo-ERN.Objective: To determine the extent of engagement in registries of Endo-ERN members.<p cl...

Urinary gonadotrophins as markers of puberty in girls and boys during late childhood and adolescence: Evidence from the SCAMP Cohort

Spiers Alexander , Patjamontri Supitcha , B Smith Rachel , Shen Chen , B. Toledano Mireille , Faisal Ahmed S

Introduction: Urinary gonadotrophins measurement is a noninvasive method for evaluation of pubertal development and may have utility in population studies.Objectives: To investigate the utility of urinary gonadotrophins as a noninvasive biomarker of puberty in boys and girls.Methods: School-based adolescent cohort study with two time points for collecting school time urine samples ...

Does serum thyroglobulin predict thyroxine requirement during infancy in athyreosis and thyroid ectopia?

Kallali Wafa , Neumann David , Jones Jeremy , Hunter Ian , Tasker Anthony , Smith Karen , Shaikh Guftar , Donaldson Malcolm

Background: Thyroglobulin (Tg), a protein synthesized uniquely in the thyroid gland, may be elevated in primary congenital hypothyroidism (CH) due to increased TSH drive, absent in true athyreosis and Tg deficiency, and very elevated in some types of dyshormonogenesis.Hypothesis: Serum Tg at the time of newborn screening may reflect the amount of thyroid tissue present in apparent athyreosis and thyroid ectopia, and henc...

Genetics of Familial Glucocorticoid Deficiency Over the Decades: Phenotypic Variability and Associated Features

Smith CJ , Maharaj AV , Prasad R , Hughes CR , Clark AJL , Chan LF , Metherell LA

Background: Over the last 25 years more than 410 cases with suspected Familial Glucocorticoid Deficiency (FGD) have been referred to our centre for genetic testing. All cases had low or undetectable serum cortisol paired with an elevated plasma ACTH level. Our patient cohort comprises 352 families from 30 different nationalities and ranges from neonates to patients in their eighties. Mutations in the MC2R were first discovered as causative of FGD in 1...

Patterns of Thyroglobulin Levels in Infants Referred With High TSH on Newborn Screening, Compared with Iodine-sufficient Healthy Controls

Kallali Wafa , Neumann David , Krylova Katerina , Jones Jeremy H. , Smith Karen , Shaikh Guftar , Donaldson Malcolm

Background: Thyroglobulin (Tg) is exclusively synthesised by thyroid tissue and a potentially useful aid to diagnosis in congenital hypothyroidism (CH). However, its role has yet to be fully evaluated.Objective: To examine the sensitivity and specificity of Tg in helping define the etiology of CH.Patients and methods: Tg was measured in a single laboratory by Immulite 2000 chemiluminescent immunometric assay (CVs 9.8, 5.7 and 5.7% ...

Can we Standardize Sex Assignment in 45,X/46,XY Mixed Gonadal Dysgenesis?

Colindres Johanna Viau , Eugster Erica , Smith O'Brian , Gunn Sheila , Mendiratta Meenal , Karaviti Lefkothea

Background: Patients with 45,X/46,XY mixed gonadal dysgenesis (MGD) have variable phenotypes leading to both male and female sex assignments. A multidisciplinary team should guide the process of sex assignment, however a standardized approach may provide objective guidance for the team as well as a tool for settings without such resources. One of the most important considerations for sex assignment is the hormonal production, which often determines the degree of virilization. ...

The Prevalence of Congenital Malformations in Infants with TSH Elevation on Newborn Screening: the Importance of Distinguishing Between True and Transient Congenital Hypothyroidism

Ouarezki Yasmine , Mansour Chourouk , Jones Jeremy , alghanay Abubaker , Smith Sarah , Stone David , Donaldson Malcolm

Backgrounds: The prevalence of congenital malformations (CM) is higher in infants referred with capillary (c) TSH elevation on newborn screening. However, establishing the prevalence of CM ± dysmorphic syndromes in true congenital hypothyroidism (CH) requires careful distinction between true and transient CH.Objective: To determine the prevalence of CM ± dysmorphic syndromes in all infants referred with TSH elevation on newborn screening in Sco...

Trends in Median Age at Guthrie Sampling, Laboratory Receipt, Notification, and Start of Treatment for Infants with TSH Elevation on Newborn Screening

Mansour Chourouk , Ouarezki Yasmine , Jones Jeremy , Smith Sarah , Donaldson Malcolm , Mason Avril

Background: Screening for congenital hypothyroidism (CH) has virtually eradicated the severe mental handicap associated with late or absent treatment. We have previously reported two audits of newborn screening for CH between 1979 and 2003 showing significant improvement from the first to more recent period.Objective and hypotheses: We aimed to audit the period 2004–2013 and report trends in timing of sampling, laboratory processing, delay between f...

SGPL1 deficiency, a cause of 46XY DSD and adrenal insufficiency, impairs lipid metabolism and steroidogenesis in Leydig cells

Kwong RMW , Smith CJ , Williams J , Hall C , Metherell LA , Prasad R

Loss of function mutations in SGPL1 (sphingosine-1-phosphate lyase) give rise to a multisystemic syndrome with predominating features of primary adrenal insufficiency (PAI) and steroid resistant nephrotic syndrome. Retrospective analysis of our patient cohort and the wider literature also demonstrated primary gonadal insufficiency in a third of male patients with microphallus and bilateral cryptorchidism (all with concomitant adrenal disease and high mortality in infa...

Congenital malformations in permanent and transient congenital hypothyroidism – prevalence and etiology

Ouarezki Yasmina , Shepherd Sheila , Jones Jeremy , Abubaker Alghanay A , Smith Sarah , Shaikh Guftar , Donaldson Malcolm

Background: An increased prevalence of extra-thyroidal congenital malformations in infants with congenital hypothyroidism (CH) is well established. However, accurate estimation of prevalence figures requires careful distinction between permanent and transient CH. Moreover, the mechanisms resulting in congenital malformations are not well understood.Study aim: To estimate the prevalence of cardiac, extra-cardiac and/or sy...
