Chromosome 21 is the smallest human autosome.

The gene is disrupted in six patients with X;autosome translocations or submicroscopic deletions; nine patients had point mutations.

This is the first report of a live born girl with an X-autosome translocation involving the ZIC3 region.

Methods: We report mapping of novel breakpoints of X;autosome-balanced translocations and interstitial deletions and a review of published X chromosome rearrangements.

The human Y chromosome, transmitted clonally through males, contains far fewer genes than the sexually recombining autosome from which it evolved.

Although studies have mainly focused on autosome, hitherto the influence of sex on familial transmission of hypertension has not been considered.

This is the first case of an unbalanced X-autosome translocation and the first case of an autosome trisomy to be reported in the horse.

The heterochromatic Y chromosomes did not display a higher methylation level compared to the autosomes.

Twenty-two pairs are called autosomes, the other pair is made up of the sex chromosomes.

People with mongolism, or Down's syndrome, have an extra chromosome in the twenty-first pair of autosomes.

These estimates suggest that microsatellites on the Y chromosome have mutation frequencies comparable to those on the autosomes.

All these birds were genotyped with 167 DNA markers located throughout the 26 autosomes.

A total of 356 microsatellites covering all 29 autosomes were used in the scan.

All experimental animals were genotyped with 39 438 SNPs located throughout the pig autosomes.

Sex is determined in Caenorhabditis elegans by the ratio of X chromosomes to the sets of autosomes, the X:A signal.

To localize the MROS genes, we used the flow-sorted X chromosomes and autosomes as a template for PCR with internal primers.
