A focused population profile of Sylheti Bengalis from Bangladesh, their northeastern Bengal background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Sylheti Bengalis are Bengali-region communities from Sylhet and the surrounding Surma-Barak cultural zone of northeastern Bangladesh.
Sylheti is widely spoken alongside Bengali and Standard Bengali. Sylheti identity is especially visible in the United Kingdom and other diaspora communities, but this page focuses on the Bangladesh reference.
As a genetic reference, Bengali Bangladesh Sylhet is useful for comparison with Bengali Bangladesh Southeast, Bengali, Bengali Bangladesh, Bengali Bangladesh Brahmanbaria, Bengali India, Odia Khandayat, Garhwali Rajput, Indo-Trinidadian, Kapu, and Chenchu.
In the World Genetics modern G25 comparison, the closest non-self match for Bengali Bangladesh Sylhet is Bengali Bangladesh Southeast. Other nearby references include Bengali, Bengali Bangladesh, Bengali Bangladesh Brahmanbaria, and Kumaoni Shilpkar Tamta. This gives the Bengali Bangladesh Sylhet profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Sylheti Bengali ancestry is best interpreted as northeastern/eastern Bengali, with close links to southeastern Bangladesh, Brahmanbaria, broader Bengali Bangladesh, and Bengali India references.
The heatmap should emphasize Sylhet, northeastern Bangladesh, the Surma-Barak region, southeastern Bangladesh, the wider Bengal Delta, northeastern India, and Bengali diaspora-linked comparison zones.
The closest non-self match in this World Genetics comparison is Bengali Bangladesh Southeast. Other nearby references include Bengali, Bengali Bangladesh, Bengali Bangladesh Brahmanbaria, and Kumaoni Shilpkar Tamta.
In the current modern G25 reference set, Bengali Bangladesh Southeast is the closest listed match to the Bengali Bangladesh Sylhet average after removing Bengali Bangladesh Sylhet itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Bengali Bangladesh Sylhet G25 average, giving the closest-match results a geographic view.
