Background: 46,XX DSD (Disorder of Sex Development) includes individuals with ovotestes (ovotesticular DSD (OTDSD)) or testes (testicular DSD (TDSD)). Most individuals with 46,XX TDSD carry the SRY gene. Other known causes of TDSD/OTDSD include chromosomal rearrangements involving SOX9 or SOX3 and mutations of WNT4 and a WNT regulator, R-SPONDIN 1. However, our understanding of the molecular causes of TDSD and OTDSD remain incomplete.<p ...

Background: Diabetes mellitus (DM) is one of ‘minor’ components of autoimmune polyglandular syndrome type 1 (APS1). The prevalence of DM in APS1 varies from 2.5 to 18% in different populations.Objective and hypotheses: To study disease phenotype and genotype of APS1 patients with DM.Method: All patients diagnosed with DM were selected from the Russian registry of APS1 patients. Clinical data, AIRE-gene mutations and immun...

Background: Achondroplasia is the most common cause of genetic dwarfism with a prevalence of 1/10 000 to 30 000 birth. It is a pathology of dominant inheritance linked to the mutation of the receptor gene growth factor on chromosome 4p16 fibroblastes FGFR3 responsable rhizomelic dwarfism and multiple complications likely to compromise the functional and vital prognosis of patients.Objective and hypotheses: Find the frequency of neurological complications...

Background: Mucopolysaccharidosis 6 (MPS6) (or Maroteaux–Lamy syndrome) is a rare genetic disease characterized by progressive systemic disease caused by a deficiency of N-acetylgalactosamine 4-sulfatase which causes an accumulation of dermatan sulfate (DS). It is due to mutations in the BRSA gene, located on chromosome 5. In severe cases, the accumulation of DS in the body cells occurs mainly in bones, joints, eyes, heart and brain. Its association with anterior...

Background: Ovarian sex differentiation network involves a panoply of interacting factors. Yet, no single sex-determining factor has been identified to be an equivalent of SRY or SOX9 in the testis. Recently, data suggested CBX2 as a pioneer regulator promoting testis development. In addition to its implication in ovary pathway differentiation which remains unclear.Objective and hypotheses: To deepen our understanding of the regulatory network that under...

Background: Diabetes mellitus (DM) is a chronic metabolic disorder requiring daily care to prevent both acute and chronic complications. Healthcare providers are challenged to manage the transition of adolescents from paediatric to adult diabetes services. Until recent date, this change of the medical team was lived by teenagers as a tearing and a discontinuity of the medical care.Objective and hypotheses: While centres providing structured integrated pa...

Background: Hyperthyroidism is considered to be rare in children; its clinical profile is different and the most cause is Grave’s disease (GD).Objective and hypotheses: To evaluate clinical features and evolution of childhood hyperthyroidism.Method: Longitudinal retrospective study of children diagnosed with hyperthyroidism in an endocrinology unit in a children hospital in Tunisia.Results: Seven cases o...

Background: APS type 1 is known to be associated with autoimmune gastroenterological pathology, which could be the very first and the worst-controlled manifestation of APS type 1. Treating these conditions in APS type 1 is debatable at present.Objective and hypotheses: We describe gastroenterological pathology in7 patients with APS type 1: clinical specifics, therapy, outcomes.Methods:</str...

Introduction: Congenital hypomagnesaemia is a rare autosomal recessive disease presenting with convulsions in the newborn period. Early diagnosis and treatment are required if neurodevelopmental delay is to be prevented.Materials and Methods: Retrospective study of patients with congenital hypomagnesemia followed in our department.Objective: To document the clinical presentation, d...

Responsiveness to recombinant human growth hormone (rhGH) treatment in Turner syndrome (TS) is highly variable. Previous research has characterised genetic variants associated with rhGH response but these only have a minor impact. The relationship of these genetic variants to the blood transcriptome is unknown. The aim of this analysis was to relate unsupervised baseline blood transcriptome and genetic data from TS patients to their phenotype, karyotype and responsiveness to r...
