GO terms associated with each gene were compared between the five groups: genes previously known to be associated with deafness in human and mouse (n = 362); novel genes associated with raised ABR thresholds in the current screen (n = 38); genes with normal thresholds but abnormal waveform features (n = 27); all genes screened in the MGP screen (n = 1,211); and all genes listed in MGI (n = 33,395). The proportion of genes in each group with the high-level GO terms listed are plotted for the three categories: Cellular component, Molecular function, and Biological process. Plotted data points are given in S6 Data. ABR, auditory brainstem response; ER, endoplasmic reticulum; GO, Gene Ontology; MGI, Mouse Genome Informatics; MGP, Mouse Genetics Project.
