Background: The familial type of isolated GH deficiency (IGHD) is characterized by a variable degree of growth restriction, low but detectable GH serum concentrations. The recessive type 1A and 1B, the autosomal-dominant type 2, and X-linked recessive type 3. Phenotype-genotype correlations are notoriously difficult to be established.Objective and hypotheses: Herein, we described the variable clinical status of a family with a novel GH1 mutation which is...

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: Turner syndrome (TS) is the most common chromosomal abnormality in females (prevalence 1/2500 births). It is related to the absence or abnormality of one of the two X chromosomes. It is characterized by a short stature, gonadal failure and a many diseases that reduce life expectancy of patients.Objective and hypotheses: Report clinical, hormonal, cytogenetics, and evolutionary TS characteristics then correlate the karyotype and clinical expre...

Background: Idiopathic hypogonadotropic hypogonadism may be normosmic (nIHH) or it may be associated with anosmia, which is known as Kallmann syndrome (KS). First mutation GNRH1 was described in 2009 in patients with nIHH. Mutations of the human GNRH1 gene are a very rare cause of nIHH, with only six mutations so far described.Case: The proband is a 11.3-year-old boy who first presented at age 1 with micropenis and cryptorchidism. His p...

Background: 5α-Reductase is an enzyme that converts testosterone to dihydrotestosterone (DHT) in peripheral tissues. DHT is responsible for the differentiation of male external genitalia. Mutations in the 5α-steroid reductase type 2 gene (SRD5A2) result in incomplete masculinisation of the external genitalia in subjects with a 46,XY karyotype. The clinical spectrum of a 46,XY individual with 5α-reductase deficiency at birth can range from complete femal...

Background: The steroidogenic acute regulatory protein (StAR) has been shown to be essential for steroidogenesis by mediating cholesterol transfer into mitochondria. Inactivating StAR mutations cause the typical clinical picture of congenital lipoid adrenal hyperplasia.Objective and hypotheses: We aimed to identify causative mutations in cases presenting with adrenal failure during early infancy.Method: Consecutive cases with adren...

Background: Cushing’s syndrome in children and adolescents is rare. Its clinical and biological symptoms are severe with a significant impact on growth and puberty and poor prognosis.Objective and hypotheses: Report clinical, etiological and evolutionary characteristics of Cushing’s syndrome in children and adolescents.Method: This is a retrospective study of 45 children and adolescents with Cushing’s syndrome hospit...

Introduction: X-linked adrenal hypoplasia congenita (AHC) is caused by mutations of the NR0B1 gene encoding DAX1 on chromosome Xp21. AHC also occurs as part of a contiguous gene deletion syndrome together with Duchenne muscular dystrophy, glycerol kinase deficiency (GKD), mental retardation, or a combination of these conditions. Here, we report a male 5 years old with AHC who presented with adrenal insufficiency, GKD, and duchenne muscular dystrophy due to a mutation in the DA...

Background: Dysfunction of the parathyroid gland is a rare cause of hypocalcaemia. It may be caused by a deficiency or resistance to PTH. Generally symptomatic It can be hereditary, congenital or acquired.Objective and hypotheses: Analysis of clinical, paraclinical, etiological and progressive children’s and adolescents hypocalcaemia by parathyroid dysfunction.Method: This is a retrospective study of hypocalcaemia by parathyro...

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...
