Background: Graves’ disease (GD) involves autoimmunity against TSH receptor (TSHR) bearing cells, leading to hyperthyroidism and often orbitopathy. When hyperthyroidism is treated with radioactive iodine (RAI), exacerbation of the orbital disease can occur.Objective and hypotheses: We hypothesized that RAI has immune effects affecting the balance between auto-reactive T cells and T cells with regulatory properties.Method: We m...

Objective: Studies on 5α-reductase type 2 deficiency (5α-RD) are limited and the genotype-phenotype correlation has not been elucidated. The aim of the study was to analyze clinical and molecular characteristics, genotype-phenotype correlation in a large Chinese 5α-RD cohort.Design: Database registration study.Method: We analyzed clinical and genetic data of gene con...

Background: Implementation of neonatal screening programs for congenital hypothyroidism (CH) has reduced related nosologies and has eradicated CH-associated mental impairment. With the decrease of the TSH cut-off limits employed to avoid false negative results, milder cases of CH are diagnosed. Obviously, in a number of patients, especially among milder CH cases, thyroid dysfunction is transient. The diagnosis of transient vs. permanent CH is established in time. No specific p...

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...

Classical growth hormone insensitivity (GHI) is caused by a defect of the growth hormone receptor and is characterized by severe postnatal growth failure, craniofacial disproportion, IGF-I deficiency and normal or elevated levels of growth hormone. This is a rare condition. With the development of new genetic techniques during the last two decades other monogenetic defects resulting in milder forms of GHI have been identified. These include genes involved in the GH-IGF-I axis:...

Background: Turner syndrome (TS) is characterised cytogenetically by X chromosome monosomy, the presence of an abnormal X chromosome, or mosaicism of a 45,X or have an abnormal sex chromosome rearrangement. Girls with variant TS show no features, fewer or milder features of TS.Objective and hypotheses: We are reporting on a clinical report of a girl with a rare variant of TS (46,X,i(X) (q10)).Method: This is a case report of a 12-y...

Context: The majority of congenital isolated growth hormone deficiency (IGHD) cases are idiopathic.Recent research has shed light on the genetic aetiologies of congenital hypopituitarism. HESX1 and GLI2 are two transcription factors, amongst a cascade of other transcription factors and signalling molecules, involved in the development of the pituitary gland. Mutations in both genes have been shown to cause congenital hypopituitarism with varying phenotypes.</p...

Background: The stimulatory G-protein α-subunit encoded by GNAS exons 1–13 (GNAS-Gsα) mediates signal transductions of multiple G-protein-coupled receptors including arginine vasopressin (AVP) receptor 2 (AVPR2). To date, various germline-derived loss-of-function variants of maternal and paternal origin have been found in pseudohypoparathyroidism type Ia and pseudopseudohypoparathyroidism respectively, and specific somatic gain...

Context: Delayed TSH elevation (dTSH) is defined as elevated TSH in the second neonatal screen following normal TSH in the initial screen. The clinical outcome of newborns with dTSH is not entirely elucidated, although several studies have suggested a full recovery in most cases.Objective: We aim to elucidate the natural history of dTSH in a group of neonatal intensive care newborns. In addition, we aim to define clinica...

Context: Higher frequency of atypical gender identity, non-heterosexual fantasies and sexual relationships, and cross-gender role behavior has been reported in females with the more severe salt wasting form of congenital adrenal hyperplasia (CAH). Data on these aspects and quality of life (QOL) among the milder, more prevalent form, the non-classic CAH (NCCAH) is scarce.Objective: To assess gender identity, gender role, ...
