Genes affected

LRRCC1 (HGNC:29373): (leucine rich repeat and coiled-coil centrosomal protein 1) This gene encodes a centrosomal protein that maintains the structural integrity of the centrosome and plays a key role in mitotic spindle formation. The encoded protein contains an N-terminal leucine-rich repeat domain and a C-terminal coiled-coil domain. It associates with the centrosome throughout the cell cycle and accumulates on the mitotic centrosome. [provided by RefSeq, Mar 2017]

E2F5-DT (HGNC:55393): (E2F5 divergent transcript)
