Novel Mutations and Mutation Combinations of TMPRSS3 Cause Various Phenotypes in One Chinese Family with Autosomal Recessive Hearing Impairment

Figure 4

Genomic structure of TMPRSS3 based on the open reading frame (NM_024022.2) containing 13 exons (black rectangles). The positions of 32 TMPRSS3 mutations are shown both at the gene (top) and at the protein level (bottom). The protein diagram depicts the predicted functional domains and sequence motifs. The mutations identified in this study are highlighted in red. TM, transmembrane domain; LDLRA, LDL receptor-like domain; SRCR, scavenger receptor cysteine-rich domain; serine protease, trypsin-like serine protease domain.
