Background: epidermal growth factor (EGF) stimulates cell growth and differentiation through its receptor EGFR. Cross-talking between the GH and EGF signaling pathways is important for normal cellular development. GH transduction defect (GHTD), a clinical disorder characterized by impaired STAT3 phosphorylation due to excessive GHR degradation, is caused by over-expression of the E3 ubiquitin ligase, CIS.Induction of GHTD fibroblasts with 200 ng/ml hGH (GH200) and silencing mR...

Background: The commonest cause of 46, XX disorders of sex development (DSD) is congenital adrenal hyperplasia (CAH). We report two female virilised siblings with uncontrolled CAH who were reared as boys since birth. Different team members were involved in management. We discuss here gender reassignment and the psychosocial implications from Islamic perspectives.Case reports: An eight and 11 years old severely virilised CAH Yemeni girls were raised as bo...

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...

Background: Mutations in the nicotinamide nucleotide transhydrogenase (NNT) gene are a rare cause of primary adrenal insufficiency (PAI), as well as cardiomyopathies and functional impairment of the gonads.Objective: Despite the description of different NNT mutations in homozygosis and compound heterozygosis in PAI patients, it remains to be clarified to which extent the function and expression of the m...

Introduction: Variants in the N-terminal of the Indian-hedgehog gene (IHH) have been associated with Brachydactyly type-A1 (AD) and Acrocapitofemoral dysplasia (AR), only three of which have been functionally studied. However, heterozygous IHH variants, majority classified as variants of unknown significance (VUS) are being increasingly identified, not only in the N-terminal but also in the uncharacterized C-terminal, by NGS, in individuals with short...

Objective: Lifetime risk of having Type 1 Diabetes Mellitus [T1DM] increases when having a blood relative with T1DM. A Finish study reports 12.2% and 11.9% of T1DMs having a first degree relative [FDR] and second degree relative [SDR] with T1DM[1]. Data from India regarding proportion of children with T1DM FDR/SDR is non-existent. Objective is to find out the same.Methods: We examined the electronic database of 902 T1DM ...

The incidence of TIDM varies greatly between different countries and regions. In Navarre, located in the north of Spain, at the western end of the Pyrenees, there has been a clear increase in the incidence of TIDM, from 13,5 cases per 100000 in the decade 1990-2000 to 20,1 cases per 100000 between 2006-2011. We wonder if this upward trend has continued in recent years. Our hospital is a reference center for Pediatric Endocrinology in Navarre.Obje...

Background: Human milk is considered the most advantageous source of nourishment for infants. Although there is a growing body of evidence showing that human milk feeding fosters early neurodevelopment, the underlying process is still not completely known. Indeed, clinical and animal research has linked human milk to enhanced myelination in the infant's central nervous system, however, access to human oligodendrocytes and neurons in the early stages of develop...

Introduction&Aim: Activation of mechanistic target of rapamycin (mTOR) as a major regulator of adipogenesis and lipid accumulation is controlled by upstream regulators hamartin/tuberous sclerosis complex (TSC) 1 and tuberin/TSC2. Hamartin and tuberin form a protein complex that inhibits signal transduction to mTOR. The impact of TSC1 deficiency is not clearly defined in human adipose tissue. We identified a likely pathogenic TSC1 splicing variant in a lipo...

Background: The etiology of central precocious puberty (CPP) still remains unknown. The abnormal expression of Fat mass and obesity-associated (FTO)-mediated N6-methyladenosine (m6A) has been confirmed to play the crucial roles in CPP. This study aimed to explore the mechanism of FTO-mediated m6A modification of brain-derived neurotrophic factor (BDNF) on CPP with puberty onset.Methods: The qRT-PCR and immunofluorescence...
