Question: 1 / 400

What congenital condition is indicated by an infant being born with a small skull, thick draped neck, and a protruding tongue?

Turner syndrome

Down's syndrome

The condition characterized by an infant being born with a small skull, thick draped neck, and a protruding tongue aligns with the characteristics of Down's syndrome, which is also known as Trisomy 21. Infants with Down's syndrome often exhibit distinctive physical features, including microcephaly (small head), hypotonia (decreased muscle tone leading to neck drooping), and an enlarged tongue that may protrude. Other common physical traits include slanted eyes, a flat nasal bridge, and a single transverse palmar crease.

Understanding these features is crucial for identifying individuals with Down's syndrome early in life. Early diagnosis can facilitate access to education, healthcare, and resources that support development and help manage any associated medical issues. The other options listed refer to different congenital conditions, which present with their own unique set of characteristics and would not typically present with the symptoms described in the question.
