Institute for Graduate Studies in Science and Engineering, 2014. Synonymous mutation LMNA c.346C>T was identified in MD family. In Epilepsy family no disease locus could be identified. Three mutations were identified in HBT family: frameshift p.E138Vfs*93 in CARHSP1, missense p.Y193C in RGS22 and p.E363G in METTL22. Stopgain mutation SRD5A3 p.W19X was found in CDG family, missense mutation p.R1820W in MHY7 was identified in MSM family, and frameshift mutation p.N116Qfs*2 in DES in DDM family. The study families were afflicted with Congenital Disorder of Glycosylation (CDG), Myosin Storage Myopathy (MSM), Desmin Deficiency Myopathy (DDM), Hereditary Brain Tumors (HBT), Epilepsy, or Muscular Dystrophy (MD). In this study, identification of the disease loci and the causative gene defects for six inherited disorders were attempted. After the identification of the disease gene locus by linkage analysis, exome sequence analysis can be applied to find the causative mutation at the candidate locus. Whole exome sequencing is a very efficient method for the identification of the causative mutation. For a recessive disease, a consanguineous family is important for the identification of the disease locus since the affected individuals share the disease haplotype in the homozygous state, descending from a single ancestor. Linkage analysis is one of the most powerful methods used to map a disease gene locus. Identification of the genetic basis of a hereditary disease provides important information about the molecular mechanism of the disease and the function of the gene and could contribute to the development of therapeutic means. Starting from whole exome fastq files: Data QC, Adapter Trimming, Reference Genome Alignment, SAM/BAM Validation. Such datasets often need sophisticated bioinformatics expertise.Graduate Program in Molecular Biology and Genetics. Whole Exome Sequencing end-to-end pipeline. WGS produces large datasets that are more complex to analyze in comparison to WES datasets. WGS requires more sequencing reagents than WES, but WES requires additional preparation reagents (probes) and extra protocol steps (hybridization). Of single-nucleotide variants (SNVs) and indels―common in population genetics, with genetic diseases, and cancer genetics research. This is important for researchers requiring comprehensive coverage Since such a smaller percentage of the genome is sequenced through WES, a deeper sequencing coverage of regions of interest (ROIs) can be achieved.
If there is a chance the disease you are studying is associated with such variation, WGS is the better option or alternatively,Ī customized exome panel can be utilized. Whole genome sequencing captures variation in any area of the genome, including non-coding regions.
Key differences between the two workflows include: Whether you choose to perform WGS or WES will depend on a number of factors. Sequencing only exons (whole exome sequencing WES) is cheaperĪnd faster than sequencing the entire genome. The areas of the genome that encode functional proteins are called exons. Of the roughly 3 billion base pairs in the human genome, just 1–2% are translated into functional proteins. However, sequencing entire genomes remains This is a powerful way to uncover genomic variation, including disease-associated mutations.
