You may get your somehow accurate (not: medical grade accurate) raw DNA sequence from Ancestry DNA kit. Why from Ancestry and not other similar services like 23andme? Because they probably have the best accuracy for the money.
You may then submit your DNA code to https://promethease.com/ that builds a personal DNA report based on connecting a file of DNA genotypes to the scientific findings cited in SNPedia.
You may learn a few things about yourself and your kids, which may also include severe conditions which could unfold in the future.
