Gene Mutation Cause No Fingerprints

Fingerprints are rigid pattern on a tip of the finger. Everybody has unique fingerprints. Two identical twins could share their DNA; nevertheless, we won’t find a person with similar fingerprints. New studied reveal By American Journal of Human Genetics that person born without fingerprints those diseases called “Adermatoglyphia”. This Adermatoglyphia is very rare gene mutation of skin disorders. Lately, research entitled this mutation “immigration delay disease”, because without fingerprint it hard to enter different countries.

Generally in the womb, fetus begins to progress fingerprints after 24 weeks of gestation that patterns called dermatoglyphs which persist throughout life. Though researchers are uncertain that when mutation occur in one particular gene which allows in some people to skip the processes of forming fingerprints during development. Researchers study on Swiss family who are affected by Adermatoglyphia.  After doing genetic analysis of family’s member, nine members don’t have fingerprints. Comparisons between affect and unaffected member, researcher found mutation in gene called “SMARCAD1” causes the Adermatoglyphia. SAMRCAD1 is encoded by protein, affected person have very short version expressed in the skin and they lack fingerprints. Hence, affect person also produced less number of sweat glands, say researchers.

 

 I am concern about people who doesn’t have fingerprint, because they have really hard time grabbing anything or holding a cup of glass. It would be terrifying for those people without fingerprints. It can cause lot of difficultly when they want to move to different countries.
