Commonest overgrowth syndromes

Abstract

Overgrowth syndromes, although rare, are diagnosed more frequently lately. Major progress, such as the identification of genetic causes, has recently enhanced the delineation of the characteristic and noncharacteristic manifestations, phenotype-genotype correlations and knowledge of the underlying pathophysiologic mechanisms. This review provides a summary of the most important overgrowth syndromes aiming to familiarize the treating physician with the cardinal clinical features involved in these syndromes that encompass overgrowth, but also have a variety of other clinical manifestations (neurologic, musculoskeletal, skin, and accompanying tumors).
