Microcephaly, also known as microencephaly, is related to primary autosomal recessive microcephaly and primary microcephaly. An important gene associated with Microcephaly is ASPM (Assembly Factor For Spindle Microtubules), and among its related pathways/superpathways are Cell Cycle, Mitotic and DNA Damage. Affiliated tissues include brain and cortex, and related phenotypes are Negative genetic interaction between MUS81-/- and MUS81+/+ and Reduced mammosphere formation
