Introduction: Le diabète de type 1 est l’endocrinopathie la plus fréquente chez l’enfant. Son incidence est en nette progression dans le monde. L’enfant diabétique nécessite une hygiène de vie adaptée et le suivi par une équipe pluridisciplinaire composée de pédiatre spécialiste en diabétologie, psychologue, diététicien, infirmier spécialisé.Objectif: Determiner les...

Background: The clinical phenotype of the chromosome 2q31 deletion syndrome consists of a variety of limb abnormalities and other skeletal defects, craniofacial dysmorhic features, developmental delay, and other not specific congenital anomalies.Objective and hypotheses: To describe a patient with 2q31.1 microdeletion syndrome and short stature, diagnosed with GH deficiency.Method: We describe a 5 years and 4 months girl with devel...

Background: Septo-optic dysplasia (SOD) is a rare congenital anomaly, clinically heterogeneous, combining optic nerve and pituitary gland hypoplasia, midline abnormalities of the brain, including absence of the corpus callosum and septum pellucidum. The diagnosis is made when two or more features of the classic triad are present. HESX1, SOX2, SOX3, FGF8, FGFR1, PROKR1, SHH, are implicated in the etiology of SOD.Objective and hypotheses: Description of a ...

Background: We report clinical and molecular cytogenetic characterization of a 13-year-7-month-old boy with a Sotos-like phenotype and de novo NFIX deletions and review the literature.Result: A whole exome sequencing revealed in the present patient with unique clinical phenotypes a de novo frameshift mutation c.570-573delATCA (p.S191Ifs*19) in NFIX gene in 19p13.2.Discussion: The p...

Background: Newborn screening for CAH is effective in identifying the severe cases; however, the high rate of false-positive (FPR) results remains an important issue. Therefore, positive neonatal results must be confirmed by serum 17OHP levels, which present a great overlap among all forms.Objective and hypotheses: To evaluate the utility of molecular analysis to improve CAH diagnosis in NBS program.Method: Between 1999 and 2014, 8...

The WT1 gene has a crucial role in the genesis of the bipotential genital ridge and subsequently in the specification of the Sertoli cells of testis. Mutations involving the WT1 gene are associated with a wide range of phenotypes impacting testis-determination and development including Denys-Drash syndrome, Frasier syndrome and Meacham syndrome. Here, we describe two sibs with DSD carrying a de novo mutation in the WT1 gene. A girl was born with Prader IV intersex genitals. Cy...

Immune dysregulation-polyendocrinopathy-enteropathy-X-linked syndrome (IPEX) is caused by mutations in the gene that encode for the transcription factor FOXP3. IPEX is a rare, often fatal disease. However, several cases present later onset, mild forms or less common clinical manifestations. We report a case who had de novo mutation of FOXP3 causing neonatal diabetes but without other features of IPEX syndrome. An 8 days old male, late preterm at 36 weeks, low birthweight 2200g...

Background: Congenital hypogonadotropic hypogonadism (CHH) is caused by impaired function of GnRH neurons, which clinically manifests by incomplete or absent puberty and infertility. The phenotype may be broader with other developmental anomalies such as anosmia, which is known as Kallmann syndrome. To date, there are more than 40 genes in which mutations underlie CHH. Cornelia de Lange Syndrome (CdLS) is characterized by facial dysmorphia, psychomotor delay, ...

Objectives: To present Chung-Jansen Syndrome or CHUJANS by a de novo variant in the pleckstrin homology domain-interacting protein (PHIP) gene and compare the clinical phenotype with previous case reports; ②To provide a novel genetic detection methods with whole-exome sequencing(WES) and whole genome sequencing(WGS) and Sanger sequencing for rare genetic diseases.Patients and methods: Following collecting clinical...

Introduction: The main role of Vitamin D (VitD) is the regulation of calcium, which is also regulated by the parathyroid hormone (PTH), and phosphate metabolism. The main source of the more biologically active 25-hydroxy-Vitamin D3 (25OHVitD3) comes from the action of ultraviolet light on the skin.Aim: To determine if there are differences in concentrations of 25OHVitD3, calcium and PTH in school-aged children throughout...
