Genes affected

TRIO (HGNC:12303): (trio Rho guanine nucleotide exchange factor) This gene encodes a large protein that functions as a GDP to GTP exchange factor. This protein promotes the reorganization of the actin cytoskeleton, thereby playing a role in cell migration and growth. Alternative splicing results in multiple transcript variants.
