Auditory phenotype of mouse Tmc1 p.T416K; Tmc2+/+. A, Fixed whole mounts of mid-region of cochleas of P30 Tmc1+/+ (top row) and Tmc1 p.T416K/+ (bottom row) labeled with phalloidin (Actin), calbindin28K (cell somas) and merge. Note OHC loss in mutant. B, ABRs thresholds of P30 wild-type, Tmc1 p.T416K/T416K homozygote, and Tmc1 p.T416K/+ heterozygote showing dominant phenotype. C, DPOAEs thresholds for Tmc1+/+ (black symbols, N = 6) and Tmc1 p.T416K/+ (red symbols, N = 8). D, Hair cell survival in P30 Tmc1 p.T416K/+ heterozygote. For each cell type, ∼100 cells along the cochlea were included in the count to construct average. In each panel, the mean +/− SD is plotted.
