Genes affected
CHAMP1 (HGNC:20311): (chromosome alignment maintaining phosphoprotein 1) This gene encodes a zinc finger protein that functions as a regulator of chromosome segregation in mitosis. The encoded protein is required for correct alignment of chromosomes on the metaphase plate, and plays a role in maintaining the attachment of sister kinetochores to microtubules from opposite spindle poles. Mutations in this gene are associated with an autosomal dominant form of intellectual disability. [provided by RefSeq, Jul 2017]
