Females with residual pyruvate dehydrogenase activity will have no uncontrollable systemic lactic acidosis and few, if any, neurological symptoms. Conversely, females with little to no enzyme activity will have major structural brain abnormalities and atrophy. Males with mutations that abolish, or almost abolish, enzyme activity presumably die ...
20,22-Desmolase (P450scc) deficiency: blocks production of all steroid hormones from cholesterol [citation needed]; 3β-Hydroxysteroid dehydrogenase 2 deficiency: impairs progestogen and androgen metabolism; prevents the synthesis of estrogens, glucocorticoids, and mineralocorticoids; causes androgen deficiency in males and androgen excess in females [citation needed]
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.

Most individuals with G6PD deficiency are asymptomatic.When it induces hemolysis, the effect is usually short-lived. [5]Most people who develop symptoms are male, due to the X-linked pattern of inheritance, but female carriers can be affected due to unfavorable lyonization or skewed X-inactivation, where random inactivation of an X-chromosome in certain cells creates a population of G6PD ...
The sex steroid deficiency produces effects similar to 17α-hydroxylase deficiency. Severely affected genetic females (XX) are born with normal internal and external genitalia and there are no clues to abnormality until adolescence, when the androgenic and estrogenic signs (e.g., breasts and pubic hair) of puberty either fails to occur or is ...
Many patients with 6-phosphogluconate dehydrogenase deficiency are carriers and have no symptoms. It has been discovered that symptoms manifest more frequently in female carriers. Depending on how severe the deficiency is, it has been demonstrated that enzyme activity is reduced by 35–65%. [citation needed]
That makes sense, since, according to the Cleveland Clinic, some of the top symptoms of vitamin D deficiency in adults are fatigue, muscle weakness, and low mood, which can lead to feeling down ...
Isobutyryl-coenzyme A dehydrogenase deficiency is a rare metabolic disorder in which the body is unable to process certain amino acids properly. [ 1 ] People with this disorder have inadequate levels of an enzyme that helps break down the amino acid valine , resulting in a buildup of valine in the urine, a symptom called valinuria .
