4. 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
