Answer the question in the picture
A 6 week old child was admitted to hospital after a failure to gain weight appropriately and subsequent examination
found them to be dehydrated. Although the child appeared phenotypically female, karyotyping showed the child to be
46XY.
Laboratory tests showed the following results:
Variable
Na* (mm)
K+ (MM)
Pregnenlone (nM)
17-OH Pregnenolone (nM)
Dehydroepiandrosterone (nM)
Cortisol (nM)
17-OH Progesterone (nM)
O 20-22 desmolase
P
17 alpha-hydroxylase
Using the information above, and with reference to Figure 1 that was provided within the congenital adrenal
hyperplasia worksheet and shows the pathways of sterlod blosynthesis, deduce the position of the metabolic
block and indicate below which enzyme is most likely to be deficient.
