Genes affected

TUBA3D (HGNC:24071): (tubulin alpha 3d) This gene encodes a member of the alpha tubulin family. Tubulin is a major component of microtubules, which are composed of alpha- and beta-tubulin heterodimers and microtubule-associated proteins in the cytoskeleton. Microtubules maintain cellular structure, function in intracellular transport, and play a role in spindle formation during mitosis. [provided by RefSeq, Oct 2011]

MZT2A (HGNC:33187): (mitotic spindle organizing protein 2A) Located in centrosome; cytosol; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
