Understanding of the molecular basis for it has been advanced in the last decade by better understanding of adrenal steroidogenesis as well as genetic studies of affected patients. Articles Cases Courses Quiz. Congenital adrenal hyperplasia, genetical approach.: Many also involve excessive or defective production of mineralocorticoidswhich can cause hypertension or salt-wasting.

In terms of diagnosis of this condition, gene sequencing can be done [6].

However, since StAR is not required for placental steroid production, pregnancy goes to term.


The diagnosis could be missed and the disease may cause to death especially in male neonate and girls with virilised severely.

Most come to medical attention between 2 weeks and 3 months of age, when after a period of poor weight gain and vomiting, they were found to be dehydrated, with severe hyponatremiahyperkalemiaand metabolic acidosis “Addisonian or adrenal crisis “. Sex steroid production may be sufficient to allow for normal sexual development as well adeenal even fertility.

Many infants born with this condition died before a method for diagnosis was recognized for proper treatment to begin. ACTH stimulates growth of the adrenal cells and increases LDL receptors to amplify adrenla of cholesterol into the cells of the adrenal cortex which make adrenal steroids, where it accumulates since little can enter the mitochondria for conversion to steroid.

Adrenal cortical hyperplasia Adrenal hyperplasia: After the CAH diagnosis, the management qdrenal disease is possible both medical and surgical. Elevated ACTH is accompanied by and contributes to marked hyperpigmentation even in the newborn period. Hypogonadism Delayed puberty Hypergonadism Precocious puberty Hypoandrogenism Hypoestrogenism Hyperandrogenism Hyperestrogenism Huperplazi illness syndrome.

In the case of lipoid CAH due to StAR deficiency, when rising gonadotropin afrenal initiate pubertydespite the inefficiency of sex steroid synthesis, the ovaries will usually make enough estradiol to produce breast development, and in some cases even menarchewith menses continuing for some years.

Unable to process the form.

Because Pscc and StAR are also essential for sex steroid synthesis in the testis and ovarythe production of testosterone by Leydig cells in the testis and androgens which leads to estrogen production by granulosa cells and progesterone by ovarian theca cells and luteal cellsrespectively, can also be impaired.

Because of all these reason neonatal CAH screening is important and necessary in our country that has high prevalence of consanguineous marriage.

In some cases, the condition is more mild with signs and symptoms of mineralocorticoid and glucocorticoid deficiency appearing after months or even years late onset.

Unlike in models of the disease in mice, patients hiiperplazi lipoid CAH do not always have enlarged adrenals due to lipid accumulation.

In vitro expression studies have been performed to define the compound heterozygous mutations on the CYP11A gene, which is localized to chromosome 15qq The adrenals are large and filled with lipid globules derived from cholesterol. In the ovary, the damage begins after pubertythe time when the ovary starts making steroid with follicle development.
