Step-by-step explanation:
The subject of this question is medicine. The signs and symptoms described in the question are characteristic of a genetic disorder called Down syndrome. Down syndrome is caused by the presence of an extra copy of chromosome 21 and is associated with various physical and developmental abnormalities.
Some of the key features of Down syndrome include shortened palpebral fissures (the opening between the eyelids), macroglossia (enlarged tongue), iris white spots (Brushfield spots), and deep palmar transverse creases (lines across the palm).
Patients with Down syndrome may also experience muscle hypotonia (low muscle tone) and incoordination. In addition, they can have abnormalities of internal organs such as congenital hypothyroidism, GI atresias (blockages in the digestive system), and cardiac atrial/ventricular septal defects (structural heart defects).
