Affymetrix SNP array data for pulmonary adenocarcinomas with or without ALK fusion. Homo sapiens

ALK fusion positive tumor constitutes a unique entitiy in lung adenocarcionmas. We compared the allelokaryotypes of ALK fusion positive and negative tumors with SNP array to get insight into the difference of genomic background of them. Overall design: Copy number analysis with Affymetrix 250K SNP arrays of 35 ALK fusion positive and 95 ALK fusion negative lung adenocarcinomas was performed with annonymous references.
