Question 11 - Single Best Answer
A one week old newborn infant is not able to go home because he has not had a bowel movement since birth. He also has features consistent with Down's syndrome. This is a chromosome abnormality (trisomy at chromosome 21) that includes a phenotype in which the child has slanted eyes, a space between the first and second toe, and a crease that spans the entire width of the palm of the hand. A biopsy specimen from his colon is shown. What is wrong with this picture?
B) There are too many cells in the submucosa
Sorry...
There is a relatively normal number of cells.
