what gene mutation causes pancreatic cancer?

1-3% of people are equipped with a mutated gene called hDEC2 which allows their body to get the rest it requires from just a few hours of sleep.
Over 99% of Koreans have a mutated gene called ABCC11 which alters the composition of sweat so that they do not produce body odor. Only 2% of Europeans have this same mutation
Scientists found that descendants of Holocaust survivors developed a stress hormone mutation. They are inherently at higher risk of anxiety and stress disorders as a result of family trauma imparting gene mutations.
The gene that was bred into tomatoes by commercial farmers to give them a uniform color had the unintended result of preventing internal sugar reactions that give tomatoes flavor. This mutation (and lack of flavor) has been bred into almost all commercial American tomatoes.
A man was cured of HIV in Germany via a bone marrow transplant from a donor whose gene mutation made him immune to HIV. That gene is relatively common in N. Europe. Researchers have speculated that the gene is the result of natural selection during diseases similar to small pox or Black Death
Redheads are more sensitive to pain because of a mutation in a gene that affects hair color and require, on average, about 20 percent more general anesthesia than people with dark hair or blond coloring.
If you have blue eyes, you may be related to every other blue-eyed person in the world. Researchers in Denmark have found that every person with blue eyes descends from just one "founder," an ancestor whose genes mutated 6,000 to 10,000 years ago. Before then, everyone had brown eyes.
Due to a mutation in the MC1R gene, redheads require a larger doses of anesthesia compared to the rest of the population.
Elizabeth Taylor had a genetic mutation of the FOXC2 gene, which gave her an extra row of eyelashes.
Scientists have found that Ozzy Osbourne has unique genetic mutations that that increase his body's endurance for hard drugs and excessive alcohol: the "genes connected to addiction, alcoholism ... all had unique variations in Osbourne, a few of which geneticists had never seen before"

Why gene mutations?

You can easily fact check why do gene mutations occur by examining the linked well-known sources.

A gene mutation allows a very small number of people to naturally sleep four hours per night, with no effects on mental or physical health. This would be evolution.

There is a mutation of the gene CCR5, called Delta 32, which introduces a premature stop codon into the gene. This premature codon means cells that have this mutation can't receive the HIV virus. Individuals with a homozygous CCR5-Delta 32 mutation are completely resistant to the HIV virus. - source

In 2009, a molecular biologist discovered a gene mutation that prevents fruitflies from getting drunk. She dubbed it "Happyhour". The same scientist had earlier identified mutations causing super-sensitivity and increased tolerance to alcohol, calling them "Cheapdate" & "Hangover", respectively. - source

If you inherit two mutated versions of the MC1R-gene, you end up a ginger. If you only inherit one, it's why you may a red beard, but dark hair.

There's a gene mutation in a strain of fruit flies called "Cheap Date" because it causes increased sensitivity to alcohol - source

Which type of mutation results when bases are added to a gene?

Later, researchers identified exactly which gene had been affected by each mutation, thereby identifying a set of genes crucial for Drosophila embryogenesis.

How gene mutation causes sickle cell anemia?

Folded ears are result of mutation in a gene that is responsible for development of cartilage. Scottish Folds are usually mixed with British Shorthairs and American Shorthairs today to avoid creating too many defects (such as rigid, stiff tail and deformity of legs and feet).

Nüsslein-Volhard and Wieschaus identified genes used in embryonic development with a series of genetic screens. They created random mutations in fruit flies using EMS. Some of the mutations affected genes involved in the development of the embryo.

Labradors are often food obsessed because of a gene mutation, making them unable to produce special appetite suppressing neuropeptides that are involved in switching off feelings of hunger after eating a meal

His studies on genes" susceptibility to mutation influenced Francis Crick and James Watson in their cellular structure of DNA.

There is a gene called sonic hedgehog; there is controversy regarding the naming of this gene due to situations where patients or parents of patients with a serious disorder are told that they or their child "have a mutation in their sonic hedgehog."

When do gene mutations occur?

White grapes are the result of a genetic mutation rather just selective breeding. All grapes originally started out as red and two small gene mutations resulted in the white grape variety being born.

Progeria is not hereditary. It is caused by a spontaneous mutation of a gene called LMNA.

Siamese cats get their color due to a gene mutation which is heat-sensitive. On the parts of the body where the temperature is above 33°C, it produces a white coat. At the extremities, when it’s lower than 33°C, it allows the production of melanin that turns the coat in these areas a dark color.

The Antennapedia gene in fruit flies, which, when mutated, can cause legs to grow out of the eyes instead of antennae

A gene that, when mutated, causes enhanced sensitivity to alcohol in fruit flies is named cheapdate

How gene mutation can produce a different protein?

Some plants (such as mustard) have genes that are necessary for the plant to sense the direction of gravity. If these genes are disabled by a mutation, a plant cannot grow upright."

Scientists were able to isolate a specific mutation of the breast cancer gene BRCA2 after mapping the genome of the entire population of Iceland, just under 335,000 citizens.

There's a mutation called "the violent gene" exclusive to finnish men that makes them way more violent and aggressive than others when intoxicated

'black panthers' arent their own species, but a name for mutated leopards, jaguars or other big cats. A change in their genes made a new type of allele. This allele stimulated production of pigment melanin and so caused their blackish fur.

Domestic and wild cats share a gene mutation that keeps their sweet taste buds from binding to sugary molecules, leaving them with no ability to taste sweetness.

Dr. Sophie Rutschmann of the University of Strasbourg discovered a mutated gene in adult fruit flies that caused them to die within two days after a certain bacterial infection. She named the genie kep1 after Kenny McCormick.

A horrible gene mutation that makes children bite off their fingers, rip out their own eyes, eat food they hate, and attack people they love.

There is an official gene in fruit flies called "Ken and Barbie" because mutating it causes flies to have no external genitalia

Humans who lack working copies of a gene known as PCSK9 have “bad cholesterol” levels (blood levels of low-density lipoprotein, associated with heart disease) that remain virtually non-existent. Scientists have only found the mutation in a handful of African Americans.

The genetic mutation that causes manx cats to often be born with no or small tails also can lead to many health problems, and the umbrella term for conditions caused by this gene is "manx syndrome"

Originally all humans were lactose intolerant. The mutation which gave adults the ability to drink milk occurred in central Europe. Most people today who are not lactose intolerant are descended from these original European mutants. It spread so quickly because it is a dominant gene.

Scientists have found a single mutation on the EDAR gene that seems to be responsible for the thicker hair shafts, more sweat glands, and smaller breast tissue observed in East Asians. All of these results were evident in mice that had the gene altered.

If you've got a red beard, but no other hair is red, the red hair itself is caused by a mutation in what researchers call the MC1R gene. Having two mutated genes gives someone all red hair, but having just one can give a person red hair in unexpected places.

Humans had a gene that produced vitamin C,but as a result of evolution and mutations over time it "broke".The remains of this non-functional gene with many mutations is, however, still present in the genomes of guinea pigs and humans.

Koreans are the least stinkiest people after sweating and have completely dry earwax, thanks to c.538A (dry-type) mutation in ABCC11 gene
