  1. This table summarises the 25 lines in which hearing phenotypes were observed which did not segregate with the targeted allele. While some of the targeted genes have been associated with a hearing phenotype (eg Sesn3 homozygotes have abnormal waveforms [11], and ISG20 has been associated with human hearing loss via genome-wide association studies (GWAS) [13, 14]), the targeted alleles did not segregate with the phenotypes reported in this paper and are not linked to the observed hearing loss described here
