ABSTRACT
<p><b>OBJECTIVE</b>To detect potential mutation in a Chinese pedigree affected with familial exudative vitreoretinopathy (FEVR).</p><p><b>METHODS</b>Clinical data of the pedigree was collected. Coding regions of candidate genes were amplified by PCR and subjected to next generation sequencing (NGS). Suspected mutations were verified by Sanger sequencing and segregation analysis.</p><p><b>RESULTS</b>Two novel heterozygous mutations (c.1695dupC and c.552-563del) were respectively detected in the LRP5 and ZNF408 genes in the proband. Both mutations were inherited from the affected mother. By Sanger sequencing, the c.552-563del mutation was also detected among unaffected members, while the c.1695dupC mutation was only detected in affected members from the pedigree and was not recorded by the HGMD, NCBI, or 1000 genome database. Upon prenatal diagnosis, the fetus was found to carry the same mutations.</p><p><b>CONCLUSION</b>Combined NGS and Sanger sequencing not only can reduce the time required for diagnosis but also enable accurate prenatal diagnosis for FEVR.</p>
