Used For

XomeDx, or whole exome sequencing (WES), can be used to identify the underlying molecular basis of a genetic disorder in an affected individual. The XomeDx test is different from other types of genetic diagnostic tests in terms of the number of genes that are sequenced simultaneously. The XomeDx test targets the protein-coding regions of the human genome, which represents ~20,000 genes and accounts for approximately ~2% of all human genetic material.
