Abstract

Sensorineural hearing loss is genetically heterogeneous. Here, we report that mutations in CIB2, which encodes a calcium- and integrin-binding protein, are associated with nonsyndromic deafness (DFNB48) and Usher syndrome type 1J (USH1J). One mutation in CIB2 is a prevalent cause of deafness DFNB48 in Pakistan; other CIB2 mutations contribute to deafness elsewhere in the world. In mice, CIB2 is localized to the mechanosensory stereocilia of inner ear hair cells and to retinal photoreceptor and pigmented epithelium cells. Consistent with molecular modeling predictions of calcium binding, CIB2 significantly decreased the ATP-induced calcium responses in heterologous cells, whereas mutations in deafness DFNB48 altered CIB2 effects on calcium responses. Furthermore, in zebrafish and Drosophila melanogaster, CIB2 is essential for the function and proper development of hair cells and retinal photoreceptor cells. We also show that CIB2 is a new member of the vertebrate Usher interactome.

I.A.B. and S.L. conducted immunocytochemistry and quantification analyses on the inner ears of wild-type and mutant mice, performed transfection assays using sensory epithelial explants and interpreted results. A.P.J.G. performed coimmunoprecipitation assays, immunocytochemistry of CIB2 in retinas and myo7a–mutant mice. K.L. and P.B.A.-E. analyzed linkage data and screened controls. S.B., A.W., M. Ayub, M. Ansar and W.A. enrolled Pakistani families. G.I.F., A.A.I. and G.P.S. performed calcium imaging in COS-7 cells, scanning electron microscopy imaging of zebrafish embryos and recording of microphonic potentials. E.K.B. and S.P.N. designed and conducted ERG studies in flies. R.Y. performed morpholino microinjections, FM1-43 dye uptake experiments, RT-PCR and startle response measurements. T.C. and D.T. generated the cib2-mutant flies and conducted light stress analysis and light microscopy imaging of fly eyes. R.S.H. performed molecular modeling. R.A.A., S.A., J.A., S.N.K. and Sheikh Riazuddin ascertained Pakistani families, obtained clinical data and performed linkage and mutational analyses. L.V.P. provided the Cib1-mutant mice. M.T. and A.S. enrolled the Turkish families and performed linkage analysis. S.M.L. supervised the work at the Baylor College of Medicine, G.I.F. supervised the work at the University of Kentucky, and T.B.F. supervised the work at the NIDCD/NIH and helped with data interpretation. Saima Riazuddin, T.B.F. and Z.M.A. wrote the manuscript; G.I.F., E.K.B., T.C., I.A.B. and S.M.L. edited the manuscript. All authors contributed to the final version of the manuscript.
