Indian Scientists Make Wide-Ranging Analysis And Annotation Of X Chromosome

...s well. The IOB analysis showed that the human X chromosome has a gene density less than other chromosomes with 43 novel protein-coding regions and 696 known genes. The researchers have been able to identify and find out the detail of pseudogenes on X chromosome. The study found 652 pseudogenes of which 26 h...

Alcohol Dependence Gene Identified

...rs all were assessed for three genes in an area on chromosome 15 that had previously been linked to alcoholism. Results showed one of the genes -- GABRG3 -- did appear to influence alcoholism risk. Researchers aren’t sure how the gene predisposes someone to alcohol dependence, but note the gene is related to ...
