BioMart query showing that the St18 gene is the only mouse gene in the first 10 Mb of chromosome 1 that is annotated as "targeting complete" by the International Mouse Mutagenesis Consortium. This involves: (A) selecting the Ensembl Mus musculus genes dataset, (B) setting the filters, (C) setting the attributes, (D) viewing the results, and (E) adding in the Gene targeting dataset to obtain just the gene that has reached the "targeting complete" status.
