Loss of ARID1A-Associated Protein Expression is a Frequent Event in Clear Cell and Endometrioid Ovarian Cancers



Abstract

Background: Inactivating somatic mutations in the ARID1A gene are described in a significant fraction of clear cell and endometrioid ovarian cancers leading to loss of the corresponding protein (BAF250a).

Conclusions:

These data confirm that loss of the ARID1A-encoded protein BAF250a is a frequent event in the genesis of clear cell and endometrioid ovarian cancers. Loss of BAF250a was not associated with clinical or epidemiologic characteristics. One explanation for these findings is that inactivation of the chromatin remodeling pathway may be a requisite event in the development of these cancers.
