Introduction: C-type natriuretic peptide receptor encoded by NPR2 gene stimulates chondrocyte differentiation and hypertrophy and extracellular matrix production within the growth plate. The phenotypical spectrum of NPR2 mutations is broad, from severe autosomal recessive acromesomelic dysplasia to milder autosomal dominant growth disorders. Some children with NPR2 variants are treated with growth hormone (GH), however, with the inco...

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: Monogenic Type 1 diabetes (T1D) is a rare disease caused by pathogenic variant in a single gene leading to dysregulation of immune system. T1D is combined with other autoimmunity like immune cytopenias, inflammatory bowel disease, rheumatoid arthritis, atopic eczema, autoimmune thyroid disease etc in these patients. Pathogenic variants in the AIRE, FOXP3, LRBA, IL2RA, CTLA4, STAT3 and STAT1 genes have...

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...
