Published November 5, 2022 Updated January 23, 2023 From Kenny the tiger to Otto the kitten, you've probably seen content about animals with Down syndrome. But what's the truth about their conditions? This giraffe numbers among the scores of animals with Down sydrome — or so the internet would have you believe. Down syndrome, a genetic disorder caused by an extra copy of chromosome 21, is not only observed in humans but also in other animals such as giraffes, chimpanzees, and dogs. This suggests that the genetic basis of Down syndrome may exist across various species, providing valuable insights into the impact of genetic variations.
10 Animals with Down Syndrome
Down syndrome is one of the most common genetic disorders among humans, occurring in approximately 1 in every 1,000 babies. However, you may wonder are there animals with down syndrome? The internet seems to think there are, as a quick search will show you some animals that have become famous for their Down syndrome-like features. A video the focal giraffe in Namibia filmed in July 2020. Note the abnormal gait and limited mobility. c A subadult male exhibiting skeletal dysplasia like syndrome on a private. Elsasser TH, Greger DL, Wittenberg S, de Vries F, Distl O. Insulin-like growth factor type-1 receptor down-regulation associated with dwarfism in Holstein calves. Mysterious Giraffe Disease Has Scientists Baffled It's unknown whether the condition, which causes bloody lesions, is contributing to the decline of the world's tallest mammals. By Kelsey Lindsey. Objective: Skeletal dysplasias, cartilaginous or skeletal disorders that sometimes result in abnormal bone development, are seldom reported in free-ranging wild animals. Here, we use photogrammetry and comparative morphometric analyses to describe cases of abnormal appendicular skeletal proportions of free-ranging giraffe in two geographically distinct taxa: a Nubian giraffe (Giraffa.

The condition, termed simply the giraffe skin disease, starts off as small nodules on the animal's skin. The nodules can develop into dry, scaly patches, which then turn into large crusty, grayish-brown lesions filled with blood or pus. Researchers are only beginning to wrap their heads around the little-understood disease. Down syndrome or Down's syndrome, also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It is usually associated with developmental delays, mild to moderate intellectual disability, and characteristic physical features. There are three types of Down syndrome, all with the same features: Trisomy 21, the most common type; Mosaic. Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21. This extra genetic material causes the developmental changes and physical features of Down syndrome. Down syndrome varies in severity among individuals, causing lifelong intellectual disability and developmental delays. Due to this, a giraffe with down syndrome can have abnormally shaped bones in its spine, arms, legs, and head. Another health issue is similar to birth asphyxia, where the down syndrome giraffe baby has oxygen cut off and doesn't develop fully. Julius, the giraffe, born at the Maryland Zoo, is an example of this condition.
Animals With Down Syndrome 6 Famous Animals That DO NOT Have Down Syndrome
In order to get oxygen up its 2-meter neck to its brain, a giraffe's heart constantly pumps blood at a pressure roughly 2.5 times higher than is normal in humans. Now, a new giraffe genome is revealing genetic alterations that allow these animals to live happily with hypertension—along with other genes linked to giraffes' unusual physique.

Scientific Name: Hominoidea Type of Animal: Primates Diet: Omnivorous Can Animals Have Down Syndrome? Yes/No (With Video) 11 Apes appear to have a genetic defect at least somewhat similar to Down syndrome on occasion, despite the fact that the presence of animals with Down syndrome has been debunked. Acute Mortality Syndrome. Acute mortality syndrome was a major cause of death in captive giraffes for decades, 34 but the frequency has decreased in recent years, largely because of improved feeding practices. Many animals died without any history of illness, others after a mild or short-term illness or stressful incident.

Skeletal dysplasias, cartilaginous or skeletal disorders that sometimes result in abnormal bone development, are seldom reported in free-ranging wild animals. Here, we use photogrammetry and comparative morphometric analyses to describe cases of abnormal appendicular skeletal proportions of free-ranging giraffe in two geographically distinct taxa: a Nubian giraffe (Giraffa camelopardalis. Down syndrome continues to be the most common chromosomal disorder. Each year, about 6,000 babies are born with Down syndrome, which is about 1 in every 700 babies born. [ Read summary] Between 1979 and 2003, the number of babies born with Down syndrome increased by about 30%. [ Read summary ]
