может, ему Exome сделать ?
засада в том, что вернуть образец в течении 7 дней не удастся ...

Important points to consider:
The saliva sample must be from the person designated, and not from any other person. If you provide a saliva sample from someone other than the person designated, the sample will not pass quality control procedures and 23andMe will not be able to return the data or provide a refund.
You must provide a new saliva sample, even if you have a stored saliva sample.
You must return the saliva sample to 23andMe within seven days of receipt of the sample collection kit.
Because supplies are limited, you may only receive one Exome Service per existing 23andMe account (i.e., if your account holds multiple profiles, only one profile may receive the Exome Service).
You will only receive raw exome sequence data, without any interpretation or reports regarding the interpretation of these data.
The Exome Service is for research, informational, and educational use only.
You must accept the Exome Service Terms of Use.
