Introduction: PTEN Hamartoma Tumor Syndrome (PHTS) is a rare disease with dominant inheritance characterized by benign (hamartoma) and malignant tumors (breast, endometrium, thyroid). Mutations in the tumor suppressor gene phosphatase and tensin homologue (PTEN) gene are responsible for the etiology.Objective: In this case report, we present an 11-year-old male who was being monitored due to follicular thyroid cancer, an...

Introduction: Gain-of-function mutations in KISS1 and KISS1R genes and loss-of-function mutations in the gene encoding the makorin RING-finger protein 3 (MKRN3) expressed only in the paternal allele are the most common genetic reasons of familial central precocious puberty (CPP).Aim: We report a case of familial CPP and a pathogen variant in the MKRN3 gene.<stron...

Aim: Arthrogryposis Multiplex Congenita type II is an autosomal dominant disease, characterized by multiple congenital contractures in the limbs without a primary neurological deficit. The most frequently observed clinical features are triangular face, palpebral fissures facing downwards, clarity in nasolabial folds, small mouth, high palate, adherent ear lobes, short stature, camptodactyly, ulnar deviations in the fingers, vertical talus and/or talipes equinovarus.<p clas...

Aim: Resistance to thyroid hormone (RTH) is a disease characterized by decreased sensitivity to thyroid hormone in the peripheral tissues such as cell membrane, metabolism, or nuclear receptor. In THRB gene mutation induced RTH, the effect of T3 on TRβ mutant receptors in the liver and the pituitary decreased, on TRα receptors located in the brain and heart increased. Triac’s activity is similar to T3.Case: A 1-month-old girl patient was a...

Magnetic resonance imaging (MRI) of the brain in disorders of sexual development (DSD) is still relatively scarce despite the opportunities it offers for understanding the influence of sex hormones on emotion and cognition. In this talk I will give an update on current structural and functional MRI research in different DSDs such as Klinefelter syndrome, Turner syndrome, Congenital Adrenal Hyperplasia, or Familial Male Precocious Puberty. Finally, parallels will be drawn to cu...

Background: Silver Russell syndrome (SRS) is characterized by low birth weight, severe postnatal short stature and distinctive facies. In ~50% of patients, (epi)genetic alterations can be detected (~40% hypomethylation of H19 on chromosome 11, ~10% maternal uniparental disomy (UPD) 7). As SRS patients are usually born small for gestational age (SGA), they are treated with GH to improve height. However, data on long-term effects of GH treatment in SRS patients are very limited....

Background: Growth hormone (GH) treatment is indicated for children who are born small for gestational age (SGA) and fail to achieve sufficient catch-up growth during infancy and remain short throughout childhood.Aims: To evaluate the effect of GH treatment in a large, multicentric, Portuguese SGA children cohort and to analyze for correlation between GH treatment response and clinical factors.<str...

Background: The aim of our study is to determine the relation of vitamin D levels (25(OH)VD) with body-mass index (BMI), age and month of extraction in pediatric patients.Materials and Methods: We present a retrospective review of medical records of patients under 18 years of age visited by the Children's Endocrinology Service (overweight and obesity) and ambulatory pediatrics (healthy and normal weight children) at ...

Introduction: Hematopoetic progenitor stem cells (HSCs, CD133+/CD45+) and very small embryonic-like stem cells (VSELs, CD133+/CD45−) can differentiate into specific immune cells. Some studies suggest that levels of HSCs and VSELs change during therapy with growth hormone (GH) or insulin-like growth factor 1 (IGF-1). GH deficiency (GHD), an endocrine disease connected with insufficient production of GH by pituitary gland, is tre...

Introduction: Complete ALS deficiency (ALS-D), caused by inactivating mutations in both IGFALS gene alleles, presents severe IGF1 and IGFBP3 deficiencies associated to moderate growth retardation.Aim: To characterize the molecular defect in a family where the index case and his father presented short stature and IGF1 and IGFBP3 deficiencies.Methods: IGF1, IGFBP3, and GH serum levels were determined by CLIA, ALS by ELISA an...
