The second most commonly mutated gene in primary microcephaly (MCPH) patients is wd40-repeat protein 62 (wdr62), but the relative contribution of WDR62 function to the growth of major brain lineages is unknown.
Human WDR62, which is localized in the cytoplasm including the centrosome, is known to be responsible for primary microcephaly; however, the role of WDR62 abnormality in cancers remains largely unknown.
