Final answer:
Common symptoms of newborns with Down's Syndrome include hypotonia, low-set ears, and a single palmar crease. These features are seen in infants due to the extra copy of chromosome 21, characteristic of this congenital condition. It's important to recognize the uniqueness of each individual with Down's Syndrome.
Step-by-step explanation:
Common symptoms of newborns with Down's Syndrome include hypotonia (decreased muscle tone), low-set ears, and a single palmar crease. These symptoms are characteristic of the congenital condition in which there is an extra copy of chromosome 21, also known as Trisomy 21. This extra genetic material affects the development of the child, leading to both physical and intellectual disabilities. Unlike hyperactivity or rapid weight gain, which are not commonly associated with Down's Syndrome, hypotonia is a well-known symptom that can be observed shortly after birth. Low-set ears and a single palmar crease are also common physical features in individuals with Down's Syndrome.
In addition to the physical symptoms, babies with Down's Syndrome may also demonstrate developmental delays, but they may vary in severity. Parents and healthcare providers should also be aware of potential associated conditions such as congenital heart defects and vision problems. Remember that each child with Down's Syndrome is unique, and while these are typical symptoms and features, there can be a range of experiences and challenges that come along with the condition.
