Whether used for GWA, reference, or other purposes, the ethnic ancestry of genotyped subjects is often pivotal since GWA scans can yield statistically inflated or false-positive results if cases and controls are ethnically mismatched or admixed (10); and conclusions from reference samples can be undermined by unknown ethnic differences or enhanced by accurate ethnic characterization (11).

The third focuses on the mismatch between ethnic and national populations which corroborates indications in US data that a substantial portion of Somalis in diaspora are not from Somalia and likely trace their origins to Djibouti, Ethiopia and Kenya.

In indecisive cases investigators with other ethnic backgrounds were involved and in cases of mismatch the ethnicity were kept as unknown.
