The exome is the part of the genome encoding proteins. In other words, it is one's full genome minus the so-called "junk DNA" (which may not necessarily be useless but that apparently does not encode anything).
The current 23andMe test now genotypes 1 million SNP's. The new Exome 80x will be sequencing all 50 million base pairs of the coding regions for 999$.
The main difference is that SNP genotyping merely compares one's DNA to a reference sequence, while sequencing may reveal new variants unobserved before. The latter is therefore more accurate.
This new test is almost as useful as a full genome sequence, which at the moment is only commercially available from the company Knome for 5,000 $ for orders of minimum 10 kits or 10,000 $ for a single test.
Orders of the new Exome80 test will be restricted to existing 23andMe for the time being.
