Introduction: Congenital central hypothyroidism (CCH) is a rare disease with inappropriate thyroid hormone secretion due to impaired TSH stimulation. TSH levels are not elevated; the patients are not diagnosed in TSH-based newborn screening. Biallelic variants in TRHR gene (encoding TRH receptor) are one of four genetic defects known to cause isolated CCH (THRH, THSB, IGSF1, TBL1X). The phenotype is variable but generally mild (neon...

Introduction: Familiar short stature (FSS) is a common variant of growth with heterogeneous etiology. Children with FSS are often excluded from further check-up and treatment. However, significant number of children with FSS comply even with the European criteria for growth hormone (GH) therapy – patients with SHOX-deficiency, growth hormone deficiency (GHD) or these born short for gestational age (SGA). The aim of the study was to identify genetic etiology of short statu...
