Final answer:
Cri-du-chat syndrome is a genetic disorder characterized by a round face, microcephaly, and a catlike cry. It is caused by a deletion of a portion of chromosome 5. Healthcare professionals should be consulted for diagnosis and management.
Step-by-step explanation:
A newborn with a round face, microcephaly, and a catlike cry may be exhibiting symptoms of a genetic disorder called Cri-du-chat syndrome. This syndrome is caused by a deletion of a portion of chromosome 5. The round face and microcephaly are characteristic features of this condition, while the catlike cry is often attributed to abnormalities in the larynx.
In Cri-du-chat syndrome, the larynx and surrounding structures may be affected, leading to a high-pitched, catlike cry. This cry is distinct and can help in diagnosing the syndrome. Other symptoms of Cri-du-chat syndrome can include developmental delays, intellectual disability, and distinctive facial features.
If a newborn is exhibiting these symptoms, it is important to consult a healthcare professional for a proper diagnosis and appropriate management.
