Introduction: Resistance to Thyroid Hormone (RTH) is a clinical syndrome characterized by impaired end-organ responsiveness to Thyroid Hormone (TH). The cardinal features of this syndrome are elevated serum levels of free THs with normal or high TSH, often with goiter and no clear symptoms of thyrotoxicosis. Mutations in the Thyroid Hormone Receptor beta (THRB) gene constitute the most frequent cause of RTH, defined as RTHβ.<p class="abstext"...

Introduction: X-linked adrenoleukodystrophy (X-ALD) is a cause of primary adrenocortical insufficiency. It is associated with accumulation of very long chain fatty acids (VLCFA), due to peroxisome dysfunction. X-ALD is caused by pathogenic variants of the ABCD1, which encodes an ATP-binding cassette transport protein, and is inherited in X-linked recessive mode. There is no known genotype-phenotype correlation, and the degree of VLCFA elevation does n...

Introduction: /Purpose: Graves' disease is the most common cause of hyperthyroidism in children and adolescents. It is an autoimmune disorder characterized by stimulating autoantibodies, leading to increased thyroid hormone release and thyrotoxicosis. Early initiation and long-term treatment, remission, and definitive treatment with thyroidectomy or radioactive iodine present a challenge. This study aims to record the data of patients with Graves' disease foll...

Introduction: Thyroid hormone resistance (THR) is a rare disease (&ap; 1/50000) mainly due to thyroid hormone receptor beta gene (THRB) mutations, generally identified in late childhood and adulthood. We report 2 atypical cases of neonatal diagnosis of THR.Case 1: The newborn presented with neonatal respiratory distress due to a voluminous compressive goiter, requiring invasive ventilation. Thyroid function test...
