Researchers have identified 43 genomic regions associated with fingerprint patterns, highlighting the gene EVI1, involved in the limb development during the embryonic stage. This finding suggests that the fingerprints are influenced by genes responsible for limb growth, which could explain the correlation among certain fingerprint patterns and finger length.
The study was conducted by a international team of researchers, including Sijia Wang, geneticist of Shanghai Institute of Nutrition and Health, Jinxi Li, geneticist at the Human Phenomenon Institute of Fudan University in Shanghai. Her work was published on January 6, 2022 in the magazine Cell, providing new evidence on the relationship between genetics and fingerprint formation.
To validate these results, the following was performed experiments in mice where it was reduced the expression of the EVI1 gene, observing abnormal patterns on the skin of their fingers. This study provides a deeper understanding about how it fingerprints are formed and their relationship to limb development.
