Although the co-deletion of RB1 and BRCA2 was only seen in two cases, it showed a marginal trend toward association among all primary GISTs ( p = 0.066), partly reflective of their chromosomal proximity.

Similarly, variations in the IF expression levels of γ-H2AX and 53BP1 were also highly significant when compared among normal tissue and two combined groups comprising GISTs at different risk levels.
Despite the marginal trend toward significance, the frequency of RB1/BRCA2 co-deletion was even lower (~5%, 2/41) in GISTs analyzed by MLPA, indicating independent alterations of either gene in a subset of primary GISTs.
