MYO7A and deafness: In this study, we performed large-scale mutation screening of 131 known deafness-related genes, including 5 USH1 genes, in a Chinese family (no. 7162) diagnosed with USH1 and identified two compound heterozygous disease-segregating mutations in the MYO7A gene: a known missense mutation c.73G>A (p.G25R) and a novel nonsense mutation c.462C>A (p.C154X).
