Discovering Your Ancestry: Exploring 58 New Genetic Groups - 23andMe Blog

Description

AI Enhanced

This blog post from 23andMe announces a significant expansion of the company's genetic ancestry service, specifically enhancing results for customers with South American, Levantine, Sephardic, and Mizrahi genetic heritage. Published in March 2024, the update represents a major advancement in genetic genealogy, adding 58 new genetic groups across South America, North Africa, and the Middle East. This enhancement reflects 23andMe's ongoing research efforts to provide more granular and accurate ancestry information for populations that have historically been underrepresented in genetic databases, addressing a long-standing gap in commercial genetic testing services. The most substantial portion of the update focuses on the Levant region, introducing 26 new genetic groups that encompass modern-day Palestine, Lebanon, Syria, Jordan, and Israel. These groups are remarkably specific, identifying distinct populations such as "Greater Ramallah" for Palestinian Christians from the West Bank's Central Highlands, "Northwestern Lebanon" for Maronite Catholics between Beirut and Tripoli, and "Central West Syria" for people from Homs and the nearby Wadi al-Nasara region. The classifications often incorporate religious and cultural identities alongside geographical locations, noting whether populations are predominantly Muslim, Christian (including various denominations like Greek Orthodox, Armenian Orthodox, and Maronite Catholic), or Druze. Additionally, the update includes 21 new Indigenous American genetic groups in South America and 11 groups for Sephardic and Mizrahi Jewish communities spanning from North Africa and Central Asia to parts of Southern Europe, India, Iran, and Iraq. The technical achievement behind this expansion stems from 23andMe's development of new computational methods that can detect distant genetic relationships with greater accuracy, using clustering techniques that transcend traditional geopolitical boundaries. This approach allows the company to identify genetic communities based on actual shared ancestry rather than modern political divisions, which is particularly valuable for Middle Eastern and Levantine populations whose genetic heritage often spans multiple contemporary nations. The target audience includes existing 23andMe customers who may have received broad regional assignments like "Broadly Arab, Egyptian & Levantine" and will now see more specific genetic group memberships that connect them to particular communities and geographic regions. This update represents more than just a technical improvement; it acknowledges the complex genetic and cultural landscape of regions that have experienced significant migration, diaspora, and cultural exchange throughout history. By incorporating religious and cultural identifiers alongside genetic clustering, 23andMe recognizes that ancestry is not merely about geographical origins but also about the communities and traditions that have shaped genetic populations over centuries. The enhancement is particularly significant for diaspora communities, including Sephardic Jews expelled from Spain in 1492 and Mizrahi Jews from Middle Eastern and North African countries, providing them with more detailed connections to their ancestral origins across multiple continents.
