Introduction: Delayed puberty is defined as the absence of the development of sexual characteristics beyond the age of 14 for boys and 13 for girls. To better understand this pathology, we conducted a retrospective study over a period of 7 years; between 2013 and 2020, involving 11 patients with a delayed puberty, followed by a pediatric endocrinology consultation at the children’s hospital Ibn Sina in Rabat.Patients:</stro...

Background: Gordon Holmes syndrome (GHS) is characterized by cerebellar ataxia/atrophy and normosmic hypogonadotropic hypogonadism (nHH). The underlying pathophysiology of this combined neurodegeneration and nHH remains unknown.Patients and methods: We studied a cohort of multiplex families with GHS through autozygosity mapping and whole exome sequencing.Results: We identified patients from three independent families carrying loss-...

Background: Congenital generalized lipodystrophy (LCG) or Seip Berardinelli Syndrome is an autosomal resessive rare disease with a prevalence of one in 10 million live births and characterized an absence of adipose tissue and alterations in carbohydrates metabolism and diabetes mellitus, hypertrigliyceridemia, hypertrophic cardiomyopathy, hepatomegaly caused by fatty infiltration which may lead to cirrosis and polycystic ovary syndrome. The challenge is to prevent these compli...

Background: Osteogenesis imperfecta (OI) includes a group of disorders with a susceptibility to bone fractures, the presentation ranging from slightly increased fracture frequency to death in the perinatal period.Objective and hypotheses: Autosomal-dominant inheritance with type I collagen biosynthesis defects is the most common, but many autosomal-recessive genes have been previously reported.Method: Whole-exome sequencing was per...

Background: Vitamin D deficiency is now a critical issue due to its high prevalence and side effects.Objective and hypotheses:: We assessed the serum vitamin D status of obese and non-obese children and comparing their therapeutic response to identical oral vitamin D consumption in Iran.Method: This study was performed in children aged 2–14 years at Children Medical Center of Tehran in Iran. At first, the serum 25-hydroxy vita...

Objectives: Monogenic diabetes and congenital hyperinsulinism (CHI) and are common disorders of glucose-regulated insulin secretion in childhood, with 13 causative genes known for MODY and 10 causative genes identified for CHI. Genetic testing for monogenic diabetes and CHI is important for patient care. We aimed to delineate genetic and clinical manifestations of monogenic diabetes and CHI diagnosed by targeted-exome sequencing (TES).Methods: Nine proba...

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...

Background and Objectives: N-terminal-pro hormone Brain Natriuretic Peptide (NT-proBNP) and hs-Troponin T (hs-TnT) are commonly used cardiac biomarkers despite lacking a deeper understanding about influencing parameters especially in the healthy pediatric population. We previously found associations between NT-proBNP and hs-TnT and a child´s age, sex, pubertal status, Body Mass Index (BMI) and serum lipid levels. Subsequently, we explored associations wi...

McCune-Albright syndrome is a rare, sporadic disorder defined by the triad of café-au-lait spots, fibrous bone dysplasia, and endocrinopathy. The diagnosis is often made on bone or endocrine involvement, but must be suspected on the particular morphology of café-au-lait spots. We report a case of McCune-Albright syndrome diagnosed on these cutaneous signs and precocious puberty. This is a 4.5-year-old girl referred by a gynecologist for a pediatric endocrinology ...
