Summary

Story summary

Researchers from the Wellcome Sanger Institute and the National Autonomous University of Mexico studied acral melanoma in over 100 tumors from Mexican patients.
They identified ancestry-linked genetic differences, showing tumors vary in behavior and outcomes.
Tumors with higher immune gene expression were linked to better outcomes, while others grew rapidly with poorer prognosis.
The study urges broader inclusion of diverse populations to improve understanding and treatment of acral melanoma.
