FIBROUS DYSPLASIA
Developmental tumor-like lesion characterized by replacement of normal bone by an excessive proliferation of cellular fibrous connective tissue mixed with irregular bone trabiculae.
Results from mutation in GNAS 1 (Guanine nucleotide-binding protein, α-stimulating activity polypeptide 1). Severity of the condition depend on the Time during fetal or postnatal life that the mutation of GNAS1 occurs
