Complete Androgen Insensitivity Syndrome: From Bench to Bed
International Journal of Molecular Sciences
Complete androgen insensitivity syndrome (CAIS) is due to complete resistance to the action of androgens, determining a female phenotype in persons with a 46,XY karyotype and functioning testes. CAIS is caused by inactivating mutations in the androgen receptor gene (AR). It is organized in eight exons located on the X chromosome. Hundreds of genetic variants in the AR gene have been reported in CAIS. They are distributed throughout the gene with a preponderance located in the ligand-binding domain. CAIS mainly presents as primary amenorrhea in an adolescent female or as a bilateral inguinal/labial hernia containing testes in prepubertal children. Some issues regarding the management of females with CAIS remain poorly standardized (such as the follow-up of intact testes, the timing of gonadal removal and optimal hormone replacement therapy). Basic research will lead to the consideration of new issues to improve long-term well-being (such as bone health, immune and metabolic aspects a...
46 XY, Female. Complete androgen insensitivity syndrome: a case report
Journal of Education, Health and Sport
Introduction: Androgen insensitivity syndrome (AIS) is an inherited disorder of sexual development caused by mutations in the androgen receptor encoding gene. Case report: A female patient born in 1984, at the age of 17, was diagnosed with complete androgen insensitivity syndrome, during the diagnosis of primary amenorrhea. She was assigned grade 7 in the Quigley scale. Cytogenetic analysis showed a 46 XY karyotype. Gynecological examination revealed a blind ending vagina and a lack of uterus. Physical examination revealed normal breast development and scanty pubic and axillary hair. The patient kept seeing herself as a woman. At the age of 18, the patient underwent laparoscopic gonadectomy. After the procedure, the patient was under medical supervision and was taking orally 1 mg of estradiol daily. At the age of 24 patient was diagnosed with. The patient received sodium alendronate and ibandronic acid. The level of FSH was 35.50 mlU / ml and LH was 13.05 mlU/ml. Discussion: Quigley...
Case Report Complete Androgen Insensitivity Syndrome in Three Sisters
2012
Disorders of sexual development (DSD) are congenital anomalies due to atypical devel-opment of chromosomes, gonads and anatomy. Complete androgen insensitivity syn-drome (CAIS), also known as testicular feminization (TF) is a rare DSD disease. The majority of CAIS patients apply to hospital with the complaint of primary amenorrhea or infertility. Given that CAIS patients are all phenotypically female while having 46, XY karyotypes, CAIS diagnosis should be disclosed in an age-appropriate manner preferably by a mental health professional. Cases are reported here for three 46XY siblings consist-ent with CAIS.
Androgen insensitivity syndrome: a review
Archives of endocrinology and metabolism
Androgenic insensitivity syndrome is the most common cause of disorders of sexual differentiation in 46,XY individuals. It results from alterations in the androgen receptor gene, leading to a frame of hormonal resistance, which may present clinically under 3 phenotypes: complete (CAIS), partial (PAIS) or mild (MAIS). The androgen receptor gene has 8 exons and 3 domains, and allelic variants in this gene occur in all domains and exons, regardless of phenotype, providing a poor genotype - phenotype correlation in this syndrome. Typically, laboratory diagnosis is made through elevated levels of LH and testosterone, with little or no virilization. Treatment depends on the phenotype and social sex of the individual. Open issues in the management of androgen insensitivity syndromes includes decisions on sex assignment, timing of gonadectomy, fertility, physcological outcomes and genetic counseling.
Complete androgen insensitivity syndrome in three sisters: A case report
Journal of Turkish Society of Obstetric and Gynecology, 2014
Complete androgen insensitivity syndrome (CAIS) (testicular feminization) is the most common cause of male pseudohermaphroditism. The underlying main pathology is an end organ resistance to androgen stimulation, and as a result, this impairs the differentiation of the body structures and systems which this hormone affects. Inheritance of this disorder is by means of an X-linked recessive gene that is responsible for the intracellular androgen receptors. CAIS may be observed in several members of a family. For this reason, the family members of the affected individual should be screened. In this article we present a case of three sisters diagnosed with CAIS after investigating the pedigree of one of them owing to an inguinal mass and diagnosing with CAIS.

Measurements of clitoral length and clitoral to urethral distance were made and analysed for a relationship in a group of 19 women with complete androgen insensitivity syndrome (CAIS) attending a specialist clinic for adult women with disorders of sexual development. These were compared with a control group of 50 women attending hospital for a gynaecological procedure. There was a positive correlation between clitoral length and clitoral to urethral distance for women with CAIS. In contrast, a negative correlation was seen between clitoral length and clitoral to urethral distance for women in the control group. Women with CAIS had a reduced mean clitoral length compared with controls (P = 0.001), but no difference was observed for the clitoral to urethral distance between the two groups (P = 0.116).
