Further, compared with Usher syndrome, there are few differences in the spatial distribution, site, or type of variants that cause DFNB2, according to a report by Kabahuma et al.12In this research, we hypothesized that the mutations identified in the previously reported 25 DFNB2 families (Table 1) could be divided into tail region (including MF1 and MF2 subdomains) mutations and non‐tail region (including motor, IQ1‐5, and SAH subdomains) mutations (Figure 1C). Here, MYO7A is linked to Usher syndrome.
