ABSTRACT
Objective To identify the pathogenesis gene mutation of a pedigree with Cockayne syndrome.Methods The peripheral blood samples of the patient and his family members were collected and the genomic DNA was then extracted.Whole exome sequencing(WES)was performed for proband′s DNA.The disease-causing mutations were identified by bioinformatics analysis and pedigree analysis. Meanwhile,the mutations were confirmed by Sanger sequencing.Results Two novel mutations in ERCC8 gene,including c.400-2A >G and c.394_398delATGTA(p.L132fs)were identified in proband.The splicing mutation originated from his father and changed the splice acceptor site AG to GG, thus possibly caused alternative splicing.The c.394_398delATGTA(p.L132fs)frameshifting mutation was inherited from his mother.The proband′s sister also carried the same compound heterozygous mutation and had the same phenotype as proband.Conclusion The pathogenesis ERCC8 gene mutation of this pedigree with Cockayne syndrome was identified by using whole exome sequencing.
