While sequencing an entire genome is eminently doable, sequencing an exome is easier. The exome contains all of the DNA that dictates the amino acid sequences of all the proteins a cell needs to make, so any mutations that will change a protein's sequence can be found in it. It's easier simply because only about two percent of the entire genome encodes proteins. But not all disease-causing genetic mutations alter amino acid sequences.
