The abnormal spindle-like microcephaly gene (ASPM), the human ortholog of the Drosophila melanogaster "abnormal spindle" gene (asp), encodes ASPM, a protein localized at the centrosome of apical neuroprogenitor cells and involved in spindle pole positioning during neurogenesis. Loss-of-function mutations in ASPM cause MCPH5, which affects the majority of all MCPH patients worldwide. Here, we report 47 unpublished patients from 39 families carrying 28 new ASPM mutations, and conduct an exhaustive review of the molecular, clinical, neuroradiological, and neuropsychological features of the 282 families previously reported (with 161 distinct ASPM mutations). Furthermore, we show that ASPM-related microcephaly is not systematically associated with intellectual deficiency and discuss the association between the structural brain defects (strong reduction in cortical volume and surface area) that modify the cortical map of these patients and their cognitive abilities. application/pdf https://sonar.ch/global/documents/50728 eng info:eu-repo/semantics/altIdentifier/doi/10.1002/humu.23381 info:eu-repo/semantics/altIdentifier/pmid/29243349 info:eu-repo/semantics/openAccess Human mutation. - 2018 ASPM MCPH brain development brain imaging centrosome intellectual disability primary microcephaly Child, Preschool Cognition Cohort Studies Family Female Genetic Association Studies Geography Humans Infant Magnetic Resonance Imaging Male Microcephaly Mutation Nerve Tissue Proteins Autosomal recessive primary microcephaly due to ASPM mutations: An update. http://purl.org/coar/resource_type/c_6501
