The Interesting History of Dwarfism: From Worship to Ridicule

The Interesting History of Dwarfism: From Worship to Ridicule

Dwarfism is typically defined as having a height of 4 foot 10 inches or less in adulthood. Along with short stature, it can also lead to bowed legs, a disproportionately large head, and short limbs. It is most commonly caused by a genetic disorder called achondroplasia. This type of dwarfism is still rare and only seen in about 1 in 15,000 to 40,000 individuals. Because of this, the lives of those of short stature have always been very unique. Ancient Times (Egypt) Writings and imagery from ancient Egypt have shown that dwarfism may have been seen as a connection to the divine. It is thought…

Gattaca: What the Movie Got Right

Gattaca: What the Movie Got Right

The movie Gattaca was released in 1997 as a warning to all about the future that gene-editing technology could bring. It tells the fictional story of a man named Vincent who was created without the use of modern technology. Vincent dreams of becoming an astronaut but is prevented from doing so by his “inferior” genetic makeup. That is until he assumes the identity of a man whose genome had been edited, mostly freeing Vincent from the challenges of genetic discrimination. The future that he lives in, imagined by the writers and producers of the film, is inarguably unjust but maybe that imagined…

Is Everyone Related?

Is Everyone Related?

Everyone on the planet is related to everyone else on the planet. In fact, it is mathematically impossible for one individual to not share some ancestry with another individual. There is even a point in history where each person’s family tree matches from that point backward. This means that a single person is the direct ancestor of every living human. This person lived between 5300 and 2200 B.C. Most Recent Common Ancestor Everyone is much more closely related than simply sharing ancestors before the year 2200 B.C. There is another person, the most recent common ancestor, that is theorized to have lived about…

King Tut and the Reason Why He Was So Sick

King Tut and the Reason Why He Was So Sick

Tutankhamun, or King Tut, was a young man that ruled ancient Egypt for a short period during the 14th century B.C. He, unfortunately, died as a teenager and was buried in an area called the Valley of the Kings. This site is where his body was found by archaeologists in 1922. The Health of King Tut Upon the discovery of Tutankhamun’s remains, researchers also discovered that the teenage king was not in good health before his death. They found that he had a deformity in the form of a clubbed foot and that bones in some of his toes were dying due to…

Can Someone Catch Cancer?

Can Someone Catch Cancer?

The short answer is no; humans cannot catch cancer. However, human beings can catch transmissible diseases that increase the risk of cancer. Viruses There are many viruses that cause diseases known to contribute to cancer risk. For example, human papillomavirus, or HPV, can cause cervical and other types of cancers by integrating its genome into the genome of the individual that it has infected. This can stop genes from being able to produce proteins that prevent cancer. Another cancer, Kaposi’s sarcoma, can be caused by the combined effects of two viruses. These are human immunodeficiency virus and human herpesvirus-8. Human herpesvirus-8, also…

The Black Death and the Gene That Helped People Survive It

The Black Death and the Gene That Helped People Survive It

The Black Death was a pandemic, caused by the bacterium Yersinia pestis, that wreaked havoc on Europe from 1347 to 1351 A.D. During this period, King Edward III of England purchased a piece of land that he decided would be a cemetery for the victims. This burial ground, now containing over 700 people, is being used to investigate the influence that the Black Death had on human genomes. The ERAP2 Gene and the Black Death ERAP2 is a DNA sequence that is located on chromosome five. The gene codes for an enzyme that helps process foreign substances so they can be presented to the immune system.…

What Is CRISPR?

What Is CRISPR?

CRISPR, also known as CRISPR/Cas9, is a gene-editing technology used to delete, add, or alter specific regions of DNA. The system has applications in human medicine as well as other fields, including animal and plant science. What Are the Parts of CRISPR? The two parts of the CRISPR/Cas9 system are the enzyme Cas9 and a section of RNA. Cas9 is derived from bacteria that use the enzyme to cut out the DNA of viruses that have been inserted into their genomes. Cas9 finds this DNA with the help of CRISPR sequences that serve as references for what the viral DNA will look like when encountered. Scientists…

Did King Henry VIII Have a Genetic Condition?

Did King Henry VIII Have a Genetic Condition?

King Henry VIII of England reigned between the years 1509 and 1547 A.D. He produced three heirs and formed the Church of England during this time. However, he also caused extreme turmoil both within his family and within England. Between the execution of two of his six wives and his abandonment of multiple children, many scholars have wondered why his actions seemed so erratic and cruel. One of their prevailing theories is that the king suffered from a rare genetic condition called McLeod syndrome which is known to cause psychosis and irritability. The Life of King Henry VIII Henry was never meant to be king as…

The Genetics of Diabetes

The Genetics of Diabetes

Diabetes, also known as diabetes mellitus, refers to a group of conditions that impact the way that sugar is processed in the body. There are two chronic types of diabetes. These are called type 1 and type 2 and both have genetic factors. Type 1 Diabetes In order for glucose (sugar) to enter cells and be used to create energy, the beta cells of the pancreas must create a hormone called insulin. The insulin is then used to bind to insulin receptors on cells throughout the body. The interactions between insulin and its receptors unlock channels that glucose can move through in order…

The Surprising Genetics of Bridgerton

The Surprising Genetics of Bridgerton

With the recent release of Queen Charlotte: A Bridgerton Story on Netflix, interest in the historical figures that inspired its characters has skyrocketed. However, many people are unaware of the genetic disorders that plagued the real-life Queen Charlotte’s family. King George III's Disease As he does in the series, the real King George suffered with his mental health. During particularly difficult episodes, he was known to write letters with 400-word sentences as well as talk so much that foam would come from his mouth. Though doctors at the time could not diagnose the king, modern-day physicians have attempted to explain the now-deceased monarch’s condition.…
