Figure 7. Touch sensitivity in different cohorts of people suffering from the Usher syndrome.

The mean tactile acuity and vibration detection thresholds were elevated in the group of people carrying pathogenic mutations in the gene USH2A (A, B) but not in a cohort of Usher syndrome type II patients with unknown genotype where tactile acuity thresholds were lower than in the control cohort (D), and vibration detection thresholds were not significantly different (C). ^ns, not significant; * p<0.05 Student's t test.
