The same number as any other human as the condition is not caused by the absence of an entire chromosome. 90% of cases are caused by an autosomal recessive of the CYP21 allele. So far there are at least 56 identified variations at this site that can cause the many variations of CAH.

What is larger a nucleosome or chromosome?
A chromosome is made up of many genes.

How many chromosome in neem?
Chromosome number of neem 2n=2x=24
How many genes does the chromosome carry?
The number of genes varies. Most of any chromosome consists of non-coding DNA, which does not contain any genes. Each chromosome has many chromatins. One gene consists of many chromatins. Therefore, one chromosome could have many genes.
How many genes do cells obtain?
The number of genes varies from chromosome to chromosome and the number of chromosomes varies from species to species (from as few as 1 single chromosome per cell to as many 30,000 chromosome pairs per cell). Human cells have 23 chromosome pairs per cell.
Congenital adrenal hyperplasia?
DefinitionCongenital adrenal hyperplasia refers to a group of inherited disorders of the adrenal gland.Alternative NamesAdrenogenital syndrome; 21-hydroxylase deficiencyCauses, incidence, and risk factorsCongenital adrenal hyperplasia can affect both boys and girls. People with congenital adrenal hyperplasia lack an enzyme needed by the adrenal gland to make the hormones cortisol and aldosterone.Without these hormones, the body produces more androgen, a type of male sex hormone. This causes male characteristics to appear early (or inappropriately).About 1 in 10,000 to 18,000 children are born with congenital adrenal hyperplasia.SymptomsGirls will usually have normal female reproductive organs (ovaries, uterus, and fallopian tubes). They may also have the following changes:Abnormal menstrual periodsDeep voiceEarly appearance of pubic and armpit hairExcessive hair growth and facial hairFailure to menstruateGenitals that look both male and female (ambiguous genitalia), often appearing more male than femaleBoys won't have any obvious problems at birth. However, they may appear to enter puberty as early as 2 - 3 years of age. Changes may include:Deep voiceEarly appearance of pubic and armpit hairEarly development of male characteristicsEnlarged penisSmall testesWell-developed musclesBoth boys and girls will be tall as children but much shorter than normal as adults.Some forms of congenital adrenal hyperplasia are more severe and cause adrenal crisis in the newborn due to a loss of salt. Newborns with these forms develop severe symptoms shortly after birth, including:Cardiac arrhythmiasDehydrationElectrolytechangesVomitingSigns and testsAbnormal salt levels in blood (serum electrolytes) and urineHigh levels of 17-OH progesteroneHigh levels of serum DHEA sulfateHigh levels of urinary 17-ketosteroidsLow levels of aldosterone and cortisolNormal or low urinary 17-hydroxycorticosteroidsX-ray for bone age (shows older bones than normal for the person's age)Genetic tests can help diagnose, confirm, and manage the disease.This disease may also affect the results of the following tests:Estriol - serumEstriol - urinePregnanediolTreatmentThe goal of treatment is to return hormone levels to normal. This is done by taking a form of cortisol (dexamethasone, fludrocortisone, or hydrocortisone) every day. People may need additional doses of medicine during times of stress, such as severe illness or surgery.The health care provider will determine the gender of a baby with ambiguous genitalia by checking the chromosomes (karyotyping). Girls with male-looking genitals will usually have surgery between ages 1 month - 3 months to correct the abnormal appearance.Parents of children with congenital adrenal hyperplasia should be aware of the side effects of steroid therapy. Report signs of infection and stress to your health care provider because the child may need more medication. Steroid medications cannot be stopped suddenly, because it may lead to adrenal insufficiency.Support GroupsNational Adrenal Diseases Foundation: www.medhelp.org/nadf/The MAGIC Foundation: www.magicfoundation.orgThe CARES Foundation: www.caresfoundation.orgExpectations (prognosis)People with this condition usually have good health. However, they may be shorter than normal, even with treatment.Males have normal fertility. Females may have a smaller opening of the vagina and lower fertility.People with this disorder must take medication their entire lives.Untreated, adrenal crisis can lead to death within 1 - 6 weeks after birth.ComplicationsAbnormal female external genitals (internal organs are normal)Adrenal crisis, including hyponatremia and shock (especially in newborns)Early development of male sexual characteristicsHigh blood pressureLow blood sugarShort height as an adult, despite early, rapid childhood growthSide effects of steroid medications used as treatmentTumors of the testes in adult menCalling your health care providerCall for an appointment with your health care provider if your child develops symptoms of this disorder.If you had a child with this disorder or you have a family history of this disease and you plan to have other children, talk to your health care provider before conceiving. Genetic counseling is important if you have a family history of congenital adrenal hyperplasia.PreventionParents with a family history of congenital adrenal hyperplasia (of any type) or a child who has the condition should consider genetic counseling.Prenatal diagnosis is available for some forms of congenital adrenal hyperplasia. Diagnosis is made in the first trimester by chorionic villus sampling. Diagnosis in the second trimester is made by measuring hormones such as 17-hydroxyprogesterone in the amniotic fluid.A newborn screening test is available for the most common form of congenital adrenal hyperplasia. It can be done on heelstick blood (as part of the routine screenings done on newborns). This test is currently performed in many states. Ask your doctor if it is done in your state.ReferencesWhite PC. Congenital adrenal hyperplasia and related disorders. In: Kliegman RM, Behrman RE, Jenson HB, Stanton BF.

What is congenital adrenal hyperplasia?
Congenital adrenal hyperplasia (CAH) refers to any of several autosomal recessive diseases resulting from mutations of genes for enzymes mediating the biochemical steps of production of cortisol from cholesterol by the adrenal glands (steroidogenesis). Most of these conditions involve excessive or deficient production of sex steroids and can alter development of primary or secondary sex characteristics in some affected infants, children, or adults. Only a small minority of people with CAH can be said to have an intersex condition, but this attracted American public attention in the late 1990s and many accounts of varying accuracy have appeared in the popular media. Approximately 95% of cases of CAH are due to 21-hydroxylase deficiency.Examples of conditions caused by various forms of CAH: * ambiguous genitalia, in some females, such that it can be initially difficult to determine sex * vomiting due to salt-wasting leading to dehydration and death * early pubic hair and rapid growth in childhood * precocious puberty or failure of puberty to occur (sexual infantilism: absent or delayed puberty) * excessive facial hair, virilization, and/or menstrual irregularity in adolescence * infertility due to anovulation * hypertension

How do you cure addison diseases?
There really isn't any particular way to avoid Addison's disease - it is usually an autoimmune reaction that destroys part of the adrenal glands. Other causes include medication toxicity (usually for Cushing's disease) or congenital/genetic defect.
