Human housekeeping genes are compact

... we find here that UTRs and even the encoded proteins are shorter for the HK genes. The magnitude of the difference is greater for the introns than for the exons and proteins (Table 1), which makes sense because the coding sequences and the UTRs are less susceptible to change. It should be mentioned ...

... Natural selection can affect the evolution of nearby unconstrained region across the genome that is less likely to be separated from the selected allele by recombination. For example, levels of genetic diversity are reduced in both coding genes and the regions around genes, either because purifying ...
Genome-wide scan of bipolar disorder in 65 pedigrees: supportive evidence for linkage at 8q24, 18q22, 4q32, 2p12, and 13q12.
Genome-wide scan of bipolar disorder in 65 pedigrees: supportive evidence for linkage at 8q24, 18q22, 4q32, 2p12, and 13q12.

... The parent of origin effect was studied across the genome in several ways. First, we used an approach described previously19 to divide the 65 pedigrees according to the parental lineage of the disorder, then we carried out linkage analyses with the sib_ibd routine of ASPEX (v2.2) in the two groups s ...

X-inactivation



X-inactivation (also called lyonization) is a process by which one of the two copies of the X chromosome present in female mammals is inactivated. The inactive X chromosome is silenced by its being packaged in such a way that it has a transcriptionally inactive structure called heterochromatin. As nearly all female mammals have two X chromosomes, X-inactivation prevents them from having twice as many X chromosome gene products as males, who only possess a single copy of the X chromosome (see dosage compensation). The choice of which X chromosome will be inactivated is random in placental mammals such as humans, but once an X chromosome is inactivated it will remain inactive throughout the lifetime of the cell and its descendants in the organism. Unlike the random X-inactivation in placental mammals, inactivation in marsupials applies exclusively to the paternally derived X chromosome.
