Abstract/OtherAbstract:
We have shown that nasal ciliated epithelium, which can be easily biopsied under local anesthetic, provides a good source of RNA transcripts from eight of the nine known genes that cause Usher syndrome, namely, MYO7A, USH1C, CDH23, PCDH15, USH1G for Usher type 1, and USH2A, GPR98, WHRN for Usher type 2. Furthermore, the known or predicted effect on mRNA splicing of eight variants was faithfully reproduced in the biopsied sample as measured by nested RT-PCR. These included changes at the canonical acceptor site, changes within the noncanonical acceptor site and both synonymous and nonsynonymous amino acid changes. This shows that mRNA analysis by this method will help in assessing the pathogenic effect of variants, which is a major problem in the molecular diagnosis of Usher syndrome.
