Introduction: Coffin-Siris Syndrome (CSS) is a rare multisystem genetic disorder which arises from genetic abnormalities within genes encoding for the SWI/SNF complex (ARID1A, ARID1B, DPF2, SMARCA4, SMARCB1, SMARCA2, SMARCE1). Endocrinopathies have been associated with CSS, including idiopathic short stature, hyperinsulinism, obesity, growth hormone deficiency, and cryptorchidism. Here, we describe the endocrine features of a series of children with S...
