The insertion of Velocigene cassette ZEN-Ub1 created a deletion of size 2434 bp between positions 60591533-60593966 of Chromosome 11 (Genome Build37). The gene locus is partially replaced by a cassette containing lacZ-polyA followed by a loxP-flanked hUbCpro-neo-polyA sequence. Cre-mediated recombination removed the neomycin selection cassette.
