The phenotype of this mouse has been attributed to a 7 cM transgene induced deletion, Del(19)TgN8052Mm, which includes the Pax2 and Pkd2l1. The transgene inserted into a LINE element in the distal region of Chromosome 19. The Scd1 and pale ear Hps1 genes are also deleted in Del(19)TgN8052Mm mice, along with several D19Mit markers.
