Introduction: The CCDC3 gene encodes for a protein expressed in endothelial cells and adipose tissue. Insulin increases its expression and, in turn, CCDC3 positively regulates adipogenesis and lipid accumulation. CCDC3 expression is increased in visceral adipose tissue from subjects with obesity. Gestational obesity can modify the metabolic programming in the offspring through epigenetic mechanisms. However, it is unknown whether the...

Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a protease that regulates IGF-1 availability, causes postnatal growth failure and changes in bone size and density in humans and mice. The present study aimed to determine the effects of daily administration (from PND5 to PND35) of recombinant murine (rm) PAPP-A2, in comparison to rmGH and rmIGF1, on mouse auxology and bone microarchitecture in homozygous Pappa2 knock-out (ko/ko) mice of both sexes. Hormone treatm...

Background: Marfan syndrome is an autosomal dominant genetic disorder with skeletal, cardiac, and ocular involvement. Mutations in the fibrillin-1 gene on chromosome 15 are responsible for the development of the syndrome.Objective: To present one case of neonatal Marfan syndrome.Case: The patient was a 1-day-old female neonate who was born at 36 weeks gestation via normal delivery. Her body weight was 2900 g and height 48 cm. Ultra...

Background: Sotos syndrome is characterized by overgrowth. The four mayor criteria for diagnosis are: overgrowth (accelerated bone age), macrocephaly, characteristic facial features and developmental delay. They can also present escoliosis, heart or genitourinary disease, seizures, hypotonia, cerebral malformations, feeding difficulties, hearing loss and a greater risk of tumours.Case report: A 10 months old girl was referred for overgrowth. BW and BL wa...

Background: Early genetic diagnosis in patients with disorders of sex development (DSDs) can facilitate clinical management, predict recurrence risks, and augment general knowledge. Novel techniques such as SNP microarrays, GWAS, and exome sequencing have identified mutations in the coding regions of genes linked to DSDs. In some instances, variants in non-coding regions have been associated with 46,XY gonadal dysgenesis, e.g. deletions upstream of SOX9 (PLoS One 2011...

Objective: To present a patient with hypercalcemia caused by a parathyroid adenoma and a deletion of the VDR gene.Case clinic: The case is that of a 13-year-old male who presented with hypercalcemia, muscle weakness, nephrocalcinosis, two pathological fractures and a family history of nephrocalcinosis. Physical examination was unremarkable, except the presence of a fracture of the left femur. Laboratory findings: Total s...

Introduction: Rare mutations of the ESR1gene, encoding the estrogen receptor alpha (ERα), have been shown to cause estrogen resistance in humans. To date, there are no effective therapeutic options. We report the case of a new inactivating mutation of ERα and provide evidence for a partial restoration of biological effects of estrogen.Methods: We performed clinical and biological phenotyping of the index case and sequenced the ESR1...

Background: Growth monitoring of apparently healthy children aims at early detection of severe underlying conditions. Strong empirical evidence shows that current practices of growth monitoring are suboptimal. Practice standardisation with validated tools requires answering two questions: Which conditions should be targeted? How should abnormal growth be defined?Objective and hypotheses: To obtain consensus on a short list of priority target conditions o...

Context: The mouse ERα−/− knock-out model and rare human ESR1 gene mutations identified to date have demonstrated crucial role of ERα in control of energy homeostasis and glucose metabolism. Subjects with ERα deficiency show features of estrogen resistance (ESTRR) with continuous linear growth in adulthood.Patient: We describe a 20-year-old female, with unknown family history, who presented...

Of the 67 included DSD patients, 33% were HSCs. 68% women and 32% men, with a total concordance between legal sex, current gender and chromosomal sex. Median age: 10.5 years, IQR 8-14. The most frequent clinical form was non-classical (NC) 45.5%, followed by classical with saline loss (CPS) 41%. The distribution of each clinical form according to the karyotype is significant (P = 0.013), the most frequent with XY karyotype is CPS and in NC forms all cases are XX. Med...
