Genes affected

SLC2A13 (HGNC:15956): (solute carrier family 2 member 13) Enables ATPase binding activity; myo-inositol:proton symporter activity; and protease binding activity. Involved in myo-inositol transport and positive regulation of amyloid-beta formation. Is integral component of plasma membrane. Part of cell body; cell periphery; and cell projection.
