When we spend a lot of time with dogs, we notice that they frequently exhibit behaviors that are identical to those of people. We “go together like peas and carrots,” to quote Forrest Gump. Our unique blend of similarities and differences is what makes the human-dog connection so ideal. With the down syndrome pugs this is important.
However, our similarities can have a detrimental impact, such as illnesses that afflict both dogs and people. These include, mentioning a few, some forms of cancer, diabetes, epilepsy, and congestive heart failure. Down syndrome, also known as “trisomy 21,” is a common chromosomal disorder in humans. The inevitable follow-up inquiry is, “Can dogs have Down syndrome?”
What Exactly Is Down syndrome?
It is critical to first comprehend what Down syndrome is. Every cell in the human body has a nucleus, which stores genetic material in genes. Genes hold the information that control all of our inherited traits and are organized into rod-shaped structures called chromosomes. Each cell’s nucleus includes 23 pairs of chromosomes, half of which are inherited from each parent. Down syndrome is caused by an additional whole or partial copy of chromosome 21.
What Are the Signs and Symptoms of Down syndrome?
The existence of this extra genetic material can have a variety of consequences. People with Down syndrome have some degree of intellectual impairment. However this varies greatly between individuals. The following are some of the most prevalent physical traits of Down’s syndrome:
- A flattening of the face, particularly the bridge of the nose
- Eyes that are almond-shaped and slant upward
- A narrow neck
- Small ear canals
- A tongue that protrudes from the mouth
- Tiny white specks on the eye’s iris (coloured region)
- Hands and feet too small
- A single line running across the palm of the hand (palmar crease)
- Pinky fingers that occasionally curl towards the thumb
- Muscle tenseness or sloppy joints
- In children and adults, the size is smaller.
People with Down syndrome may also have a number of medical issues. The most popular are as follows:
- Hearing impairment (up to 75 percent of people with Down syndrome may be affected)
- Obstructive sleep apnea is a condition in which a person’s breathing briefly pauses while sleeping (between 50 percent and 75 percent).
- Infections of the ears (between 50 and 70 percent)
- Eye ailments (up to 60%) such as cataracts and vision impairments that need the use of glasses.
- Birth defects of the heart (50 percent)
Is It Possible for Dogs to Have Down syndrome?
The answer to the issue of whether a dog has Down syndrome depends on how you look at it. It is believed that one in every 700 newborns born in Western nations has it. Dogs, on the other hand, are a different storey. It is significantly more unusual in dogs to have Down syndrome. Know more about the same from thanesix.com.
Dogs and humans share many genetic similarities, yet significant distinctions occur. People, for example, have 23 pairs of chromosomes, but canines have 39. As a result, replicating all or a portion of chromosome 21 would have distinct consequences in the two species.
Surprisingly, scientists are using genetically modified mice as models in Down syndrome studies. These mice have an additional piece of chromosome 16, which contains genes similar to those found on human chromosome 21. As a result, a mouse can exhibit traits comparable to humans with Down syndrome. However, keep in mind that they aren’t naturally occurring mice. They’ve been genetically changed.
