The CINs of the centromere.

Replication stress is a significant contributor to genome instability. Recent studies suggest that the centromere is particularly susceptible to replication stress and prone to rearrangements and genome damage, as well as chromosome loss. This effect is enhanced by loss of heterochromatin. The resulting changes in genetic organization, including chromosome loss, increased mutation and loss of heterozygosity, are important contributors to malignant growth.
