Genes affected

TANC2 (HGNC:30212): (tetratricopeptide repeat, ankyrin repeat and coiled-coil containing 2) Predicted to be involved in dense core granule cytoskeletal transport; regulation of dendritic spine development; and regulation of dendritic spine morphogenesis. Predicted to act upstream of or within in utero embryonic development. Located in dendritic spine. [provided by Alliance of Genome Resources, Apr 2022]
