  1. 5-alpha reductase deficiency is an inherited condition that affects sexual development. It is also known as a disorder of sex development. This condition affects individuals who are genetically male (i.e., those with one X chromosome and one Y chromosome), and results from a deficiency of the steroid 5-alpha reductase 2 enzyme
  2. Discovery of 5-alpha reductase deficiency as a syndrome of disordered male sexual development led to our molecular understanding of the role that this key enzyme plays in male sexual differentiation. This article will review the clinical and molecular history behind the discovery of 5-alpha reductase deficiency
  3. Steroid 5-alpha-reductase 2 deficiency, a 46,XY disorder of sexual development (DSD), is an autosomal recessive condition in which 46,XY subjects with bilateral testes and normal testosterone production have impaired virilization during embryogenesis due to defective conversion of testosterone to dihydrotestosterone (DHT)
  4. Children with 5-alpha reductase deficiency are genetically male (with one X and one Y chromosome and male gonads—testes). But their bodies develop with what are called ambiguous genitalia, not clearly male or female. Children with this condition are often raised as female. However, upon puberty when male hormones increase, these.

#5-alpha reductase deficiency. Visit the AIS Support Group site for an explanation of 5-ARDS (listed under Related Conditions), for an excellent bibliography and for information on support.. Different from AIS, 5-ARDS occurs due to an autosomal defect (on a chromosome other than the X or Y chromosomes) and requires two altered genes, one from the father and one from the mother 5-alpha-reductase deficiency usually produces severe male genital ambiguity with a bifid scrotum, urogenital sinus, and a clitoris like a phallus. Inadequate endocrine evaluation in newborns may fail to make a correct diagnosis and determine a gender assignment opposed to genetic and gonadal sex with possible deterioration in long-term outcomes.

People with this condition are genetically male, with one X and one Y chromosome in each cell, and they have male gonads (testes) 5-alpha-reductase is an enzyme that converts testosterone to dihydrotestosterone (DHT) in peripheral tissues. DHT is a potent androgen, necessary for the development of male external genitalia in utero. DHT deficiency results in ambiguous external genitalia at birth. The condition affects only chromosomal males (i.e., those with XY chromosomes )

Overview. 5-alpha reductase deficiency is an inherited condition that primarily affects male sexual development before birth and during puberty. People with this condition are genetically male, with one X and one Y chromosome in each cell, and they have male gonads (testes) Medical definition of 5-alpha-reductase deficiency: a genetic disorder in which males exhibit external genitalia that typically resembles that of females but in which some secondary sex characteristics (such as an increase in muscle mass and descending of the testes) develop during puberty Ordinarily when a fetus is genetically male (has 46,XY chromosomes), this is how development happens: Early in fetal development, the proto-gonads (cells that will become gonads) become testes. The testes start putting out testosterone. The fetus's body makes a chemical enzyme called 5-alpha reductase (5-AR), and the 5-AR converts some of the testosterone into dihydrotestosterone. 5-alpha-reductase Deficiency: Disease Bioinformatics. Research of 5-alpha-reductase Deficiency has been linked to Disorders Of Sex Development, Hypospadias, Pseudohermaphroditism Male, Testicular Feminization, Feminization. The study of 5-alpha-reductase Deficiency has been mentioned in research publications which can be found using our.

5-alpha-reductase deficiency - Osmosi

5-alpha reductase deficiency is a rare condition. Patients with 5-alpha-reductase deficiency do not produce enough dihydrotestosterone (DHT), a hormone which has a critical role in male sexual development, and a shortage of this hormone disrupts the formation of the external sex organs before birth The condition of 5-alpha-reductase type 2 deficiency (5-ARD) is an inherited disorder resulting in the inability to convert testosterone to dihydrotestosterone (DHT). This disorder was previously termed as familial incomplete male pseudohermaphroditism type 2, pseudovaginal perineoscrotal hypospadias

  5. To study the molecular genetics of 5-alpha-reductase deficiency (PPSH; 264600), a male pseudohermaphroditism, Jenkins et al. (1992) analyzed genomic DNA from 16 affected individuals and compared it to the cloned human cDNA for 5-alpha-reductase-1.

This is an autosomal recessive form of partial male pseudohermaphroditism where there is a deficiency of the type 2 form of the enzyme 5 alpha-reductase. 5 alpha-reductase catalyses the conversion of testosterone to dihydrotestosterone, a reaction that is essential for the virilization of the male embryo and for subsequent growth of tissues. Background. 5-alpha-reductase type 2 deficiency (5-ARD) is an autosomal recessive sex-limited condition resulting in the inability to convert testosterone to the more physiologically active dihydrotestosterone (DHT).. Because DHT is required for the normal masculinization of the external genitalia in utero, genetic males with 5-alpha-reductase type 2 deficiency are born with ambiguous genitalia Steroid 5 alpha reductase 2 converts testosterone→dihydrotestosterone (DHT). DHT is essential for normal formation of male external genitalia. 5 alpha reductase deficiency DSD is AR but only penetrant in 46,XY. 46,XX are normal females, may have late menarche Activity Description. This activity reviews 5-alpha-reductase deficiency, an important cause of ambiguous genitalia in children.
