The BBC has a fascinating story on “ The family without fingerprints Where the men in the Sarker family share a genetic mutation that causes them not to have fingerprints.
The family live in the northern Rajshahi district of Bangladesh, and not having fingerprints has led to some unique challenges. In 2010, Bangladesh made national identity cards mandatory for all adults and the database requires a fingerprint. Fingerprints also became mandatory for passports and driving licenses, and the father, Amal Sarker, had to obtain a special certificate from a medical council.
In 2016, the government made it mandatory to match a fingerprint with the national database in order to purchase a Sim card for a mobile phone. According to BBC News:
The rare disease probably affecting the Sarker family is called Adermatoglyphy. It became widely known in 2007 when Peter Itin, a Swiss dermatologist, was contacted by a woman in the country in her late twenties who was struggling to enter the United States. His face matched the photo on his passport, but customs officials were unable to register any fingerprints. Because she didn’t have one.
