Your DNA contains around 3 billion base pairs in each set of 23 chromosomes, and you have two sets, one from each parent. We all share around 99.9% of this sequence; the remaining 0.1% accounts for many of our differences.
Most of these differences are single nucleotide polymorphisms (SNPs). Scientific research has linked many of them to traits, responses to medicines or genetic susceptibility to health conditions, and this information is recorded in public databases such as ClinVar, dbSNP, Ensembl and OMIM.
Our team selects associations supported by robust evidence from large, peer-reviewed studies and combines them with your data. Each result includes a technical report with the variants analysed and the references on which it is based.
