Genes affected
GIT1 (HGNC:4272): (GIT ArfGAP 1) Enables gamma-tubulin binding activity. Involved in positive regulation of microtubule nucleation and regulation of cytokinesis. Located in several cellular components, including focal adhesion; microtubule cytoskeleton; and mitochondrion. Implicated in attention deficit hyperactivity disorder. Biomarker of Huntington's disease. [provided by Alliance of Genome Resources, Apr 2022]
ABHD15-AS1 (HGNC:49685): (ABHD15 antisense RNA 1)
