Adermatoglyphia

The rare condition has only been observed in a few families, and has no adverse effects on overall health. Researchers found that, in the case of one family with a history of adermatoglyphia, there was a mutation in the gene that coded for the protein SMARCAD1. They theorized that this protein may be an integral part of fingerprint development—a process that still isn't fully understood.
