Inverted formin-2

Inverted formin 2, INF2, is involved in actin elongation and nucleation. Mutations of the gene are responsible for two autosomal dominant disorders: focal segmental glomerulosclerosis (FSGS) and Charcot-Marie-Tooth disease (CMT). In a variable degree both disorders can be present in one patient.
