Fingerprint patterns are used to identify a person’s identity. In fact, as early as
24 weeks inside a mother’s womb, a fetus has already developed unique fingerprints. Generally,
no two people have the same fingerprints.
However,
some people do not develop dermatoglyphs or fingerprint patterns. This
condition is called adermatoglyphia .
Researchers
from Tel Aviv Sourasky Medical Center in Israel have recently discovered why
this phenomenon occurs. Headed by Dr. Eli Sprecher, the team made a test on a
Swiss family affected by adermatoglyphia. The study involved comparing the genes of the nine family members
without fingerprints to the seven family members with prints.
Results
revealed that a gene mutation
may be the cause of missing fingerprints. It was found that people
who have adermatoglyphia have shorter versions of the gene called SMARDCAD1.
This gene regulates other genes related to body development.
Not having
fingerprints may have negative effects. People with adermatoglyphia may find it
difficult to travel to other countries that require fingerprint recording.
Because of this, adermatoglyphia is sometimes called “immigration delay disease.”
People with adermatoglyphia also suffer from skin
blistering, facial tumors and lack of sweat glands in the palm. Researchers are
still investigating the reasons for these additional disorders.
