Growth is influenced by genetic, nutritional, environmental, and hormonal factors, but it proceeds in a remarkably predictable pattern characterized by a constant growth deceleration between childhood and adolescence, when the pubertal growth spurt occurs. This growth deceleration is coordinated in multiple tissues and organs in order to maintain body proportions. Growth hormone (GH)/ insulin-like growth factor type 1 (IGF1) axis and insulin are crucial stimulators of growth, ...

Differences of sex development (DSD) with asymmetrical overgrowth is a very rare condition that can be secondary to a chromosomal mosaicism (ChM). ChM is usually a post zygote event and arises when two or more cell lines with different chromosomal constitutions are present in the same individual. Usually distinctive methodologies approaches are required to reach the diagnosis. Our objective is to describe a patient with asymmetrical overgrowth and DSD and the methodological st...

Introduction: SOFT syndrome (MIM#614813), denoting Short stature, Onychodysplasia, Facial dysmorphism, and hypoTrichosis, is a rare primordial dwarfism syndrome encompassing severe growth failure of prenatal onset, craniofacial dysmorphism, sparse hair, and digital abnormalities associated with biallelic pathogenic POC1Agene variants. Phenotypic spectrum has recently been expanded to include insulin resistance (IR) and muscle cramps.<p class="abst...
