Pseudohypoparathyroidism (PHP) is an hereditary disorder characterized by resistance to parathyroid hormone (PTH) and in varying degrees to TSH, GHRH and FSH/LH, and caused by loss-of-function mutations in the GNAS gene, encoding the membrane protein Gs-alpha. Pathognomonic of these patients is a dysmorphic phenotype, called Albright's Osteodystrophy, which includes short stature, obesity, round face, mental delay, subcutaneous ossifications and brachydactyly. The most fr...

Background: Distal chromosome 16 duplication syndrome, also known as 16q partial trisomy, is a very rare genetic disorder. Smaller chromosomal copy number variants (CNVs) within the 16q region create partial trisomies, which occur less frequently than full trisomy 16q. Trisomy 16q is generally associated with a multisystemic phenotype including intrauterine growth restriction (IUGR), brain and cardiac defects, intellectual disability and an increased risk of b...

Background: Osteogenesis imperfecta / Ehlers–Danlos (OI/EDS) overlap syndrome is a rare and recently described disorder of connective tissue, characterized by mutation of COL1A1 (17q21.33) or COL1A2 (7q21.3) genes, involved in alpha-1 and alpha-2 chains of type 1 collagen synthesis. Patients with OI/EDS overlap syndrome could show a phenotype characterized by features of both osteogenesis imperfecta (bone fragility, long bone fractures, blue sclerae, sho...
