Genetic basis behind immigration-delay disease ..

I've got you under my finger … or not
We usually think of fingerprints in terms of their use in forensics: The unique character of each person's fingerprints serves as a useful means of identification whether it be for security purposes or for reliably connecting a suspect with fingerprint evidence left at a crime scene. But, why did we evolve to have fingerprints, and what are the biological processes involved in their creation? Insight into addressing these questions may be provided by studying a group of individuals who do not have fingerprints. This condition, known as adermatoglyphia, can be isolated or accompanied by additional syndromic features. In this issue, Nousbeck and colleagues report that a mutation in SMARCAD1 causes adermatoglyphia in the affected individuals of a large Swiss family.

The fingerprint research was published August 12 in the American Journal of Human Genetics.
