RBM6 (RNA Binding Motif protein 6) [GenBank Accession Number: NM_005777] was first identified by positional cloning from a small cell lung carcinoma homozygous deletion region at the 3p21.3 tumour suppressor locus [3], and, in parallel, as a differentially expressed transcript during granulocyte differentiation [4]. The gene discussed is RBM6; the disease is small cell lung carcinoma.
