The correlations between the molecular information of the tumor and the data from the microarray study were as follows: NF2 mutated by dHPLC analysis vs. not mutated; NF2 mutated by both dHPLC and MLPA P044 vs. not mutated; 22q LOH present vs. no 22q LOH; 2 or more hits in NF2 vs. 1 or no hits. This evidence concerns the gene NF2 and neoplasm.
