Damage to human chromosome 9 (of the cell's 24 pairs) where the gene that codes for E-NTPDase2 resides is known to cause eye and brain defects, such as microphthalmia — literally, small eyes.

CBX2 has aroused interest as a possible master switch for maleness because tests in human cells suggest that mutations in it can shut off a gene on the Y chromosome critical for male sexual development.

This new insight into how chromosomes are disassembled and reassembled during cell division will allow researchers to begin answering basic questions about epigenetic inheritance, as well as human disease such as chromosome disorders and cancer.

Using human T cells in culture as well as mice lacking one of these genes, YY1, they found that, indeed, the two proteins did help move Xist back to the inactive X chromosome in activated lymphocytes.

The assembly and analysis of human tumor cell genomes, many of which contain chromosome deletions, duplications and insertions, as well as single nucleotide changes, requires immense data storage capacity and high - speed computation.

«In fact, abnormal cells with numerical and / or structural anomalies of chromosomes have been observed in as many as 80 - 90 % of human early stage embryos following in vitro fertilization,» says Professor Thierry Voet from the Wellcome Trust Sanger Institute, UK, and the University of Leuven, Belgium, another senior author of this paper, «and CSV tests may expose some degree of these abnormalities.»
