A study has revealed that serum progesterone concentrations in boys (10 days to 18 years old) with 21-hydroxylase deficiency reached levels up to 10.14 ng/mL, i.e. similar to female luteal values, while in the control group of boys, average level was 0.07 ng/mL (0.22 nmol/L), with values ranging from 0.05 to 0.40 ng/mL.

Elevated 17α-hydroxyprogesterone; Classic 21-hydroxylase deficiency typically causes 17α-hydroxyprogesterone blood levels >242 nmol/L. [medical citation needed] (For comparison, a full-term infant at three days of age should have <3 nmol/L. Many neonatal screening programs have specific reference ranges by weight and gestational age because ...
Newborn screening programs initially used screening criteria based largely on criteria established by JMG Wilson and F. Jungner in 1968. [6] Although not specifically about newborn population screening programs, their publication, Principles and practice of screening for disease proposed ten criteria that screening programs should meet before being used as a public health measure.

[2] [3] With the advent of expanded newborn screening, some mothers have been identified with MCADD after their infants had positive newborn screens for low carnitine levels. [ 4 ] The enzyme medium-chain acyl-CoA dehydrogenase ( MCAD ) is responsible for the dehydrogenation step of fatty acids with chain lengths between 6 and 12 carbons as ...

One of the difficulties with ALD as a disease included in universal newborn screening is the difficulty in predicting the eventual phenotype that an individual will express. The accepted treatment for affected boys presenting with the cerebral childhood form of the disease is a bone marrow transplant, a procedure which carries significant risks.
