Chromosome, acrocentric: A chromosome (one of the microscopically visible carriers of the genetic material DNA) with its centromere (the "waist" of the chromosome) located quite near one end of the chromosome.

Down syndrome (trisomy 21) is due to an extra acrocentric chromosome, namely chromosome 21.
