[4] Half of patients with Silver–Russell syndrome do not have an identified molecular etiology which suggests the involvement of other unknown genes.

Old fruitbodies fade to tan or whitish. Each shelf may be anywhere from 5 to 60 centimetres (2 to 23 + 1 ⁄ 2 inches) across and up to 4–12 cm (1 + 1 ⁄ 2 – 4 + 1 ⁄ 2 in) thick. [2] [5] The fertile surface is sulphur-yellow with small pores or tubes and produces a white spore print. [6]
Reduced or absent sensation over the skin of the affected area [2] Ecchymosis (bruising) that progresses to skin necrosis. [2] This is because the skin changes color from red to purple and black due to clotting blood vessels [8] Rapid progression to shock despite antibiotic therapy is another indication of necrotizing fasciitis. However, those ...
