FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene is the human ortholog of the Drosophila melanogaster 'abnormal spindle' gene (asp), which is essential for normal mitotic spindle function in embryonic neuroblasts. Studies in mouse also suggest a role of this gene in mitotic spindle regulation, with a preferential role in regulating neurogenesis. Mutations in this gene are associated with microcephaly primary type 5. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, May 2011]
PHENOTYPE: Mice homozygous for protein-truncating gene trap mutations of this gene exhibit decreased body weight, microcephaly, a severe reduction in brain, testis and ovary weight, oligozoospermia and asthenospermia, and reduced fertility in both sexes. [provided by MGI curators]
