Abstract
Mutations in the phosphoinositide metabolism gene FIG4 disrupt the endosomal pathway, leading to neurodegeneration and a newly identified variant of Charcot-Marie-Tooth disorder.
Phosphorylated metabolites of phosphatidylinositol, the phosphoinositides, have long been known to play an important role in signal transduction at the cell surface. More recently, they have emerged as important regulators of the membrane-cytosol interface on a variety of intracellular organelles1, 2.
