[[http://www.uniprot.org/uniprot/ANDR_HUMAN ANDR_HUMAN]] Defects in AR are the cause of androgen insensitivity syndrome (AIS) [MIM:[http://omim.org/entry/300068 300068]]; previously known as testicular feminization syndrome (TFM). AIS is an X-linked recessive form of pseudohermaphroditism due end-organ resistance to androgen. Affected males have female external genitalia, female breast development, blind vagina, absent uterus and female adnexa, and abdominal or inguinal testes, despite a normal 46,XY karyotype.<ref>PMID:2594783</ref><ref>PMID:8413310</ref><ref>PMID:1775137</ref><ref>PMID:16129672</ref><ref>PMID:2082179</ref><ref>PMID:1999491</ref><ref>PMID:1609793</ref><ref>PMID:1426313</ref><ref>PMID:1487249</ref><ref>PMID:1307250</ref><ref>PMID:1569163</ref><ref>PMID:1464650</ref><ref>PMID:1430233</ref><ref>PMID:1316540</ref><ref>PMID:1480178</ref><ref>PMID:8224266</ref><ref>PMID:8103398</ref><ref>PMID:8281140</ref><ref>PMID:8325950</ref><ref>PMID:8096390</ref><ref>PMID:8446106</ref>[:]<ref>PMID:8162033</ref><ref>PMID:7981687</ref><ref>PMID:7981689</ref><ref>PMID:7962294</ref><ref>PMID:8040309</ref><ref>PMID:7929841</ref><ref>PMID:7993455</ref><ref>PMID:7970939</ref><ref>PMID:8830623</ref><ref>PMID:7641413</ref><ref>PMID:7671849</ref><ref>PMID:7633398</ref><ref>PMID:7537149</ref><ref>PMID:7581399</ref><ref>PMID:8723113</ref><ref>PMID:9039340</ref><ref>PMID:9001799</ref><ref>PMID:8626869</ref><ref>PMID:8768864</ref><ref>PMID:8918984</ref><ref>PMID:8683794</ref><ref>PMID:8647313</ref><ref>PMID:8809734</ref><ref>PMID:9106550</ref><ref>PMID:9160185</ref><ref>PMID:9007482</ref><ref>PMID:8990010</ref><ref>PMID:9255042</ref><ref>PMID:9252933</ref><ref>PMID:9328206</ref><ref>PMID:9302173</ref><ref>PMID:9544375</ref><ref>PMID:9698822</ref><ref>PMID:9788719</ref><ref>PMID:9610419</ref><ref>PMID:9856504</ref><ref>PMID:9554754</ref>[:]<ref>PMID:9851768</ref><ref>PMID:9627582</ref><ref>PMID:10571951</ref><ref>PMID:10221692</ref><ref>PMID:10404311</ref><ref>PMID:10022458</ref><ref>PMID:10221770</ref><ref>PMID:10590024</ref><ref>PMID:10458483</ref><ref>PMID:10690872</ref><ref>PMID:11587068</ref><ref>PMID:11744994</ref><ref>PMID:16595706</ref> Defects in AR are the cause of spinal and bulbar muscular atrophy X-linked type 1 (SMAX1) [MIM:[http://omim.org/entry/313200 313200]]; also known as Kennedy disease. SMAX1 is an X-linked recessive form of spinal muscular atrophy. Spinal muscular atrophy refers to a group of neuromuscular disorders characterized by degeneration of the anterior horn cells of the spinal cord, leading to symmetrical muscle weakness and atrophy. SMAX1 occurs only in men. Age at onset is usually in the third to fifth decade of life, but earlier involvement has been reported. It is characterized by slowly progressive limb and bulbar muscle weakness with fasciculations, muscle atrophy, and gynecomastia. The disorder is clinically similar to classic forms of autosomal spinal muscular atrophy. Note=Caused by trinucleotide CAG repeat expansion. In SMAX1 patients the number of Gln ranges from 38 to 62. Longer expansions result in earlier onset and more severe clinical manifestations of the disease.<ref>PMID:15851746</ref> Note=Defects in AR may play a role in metastatic prostate cancer. The mutated receptor stimulates prostate growth and metastases development despite of androgen ablation. This treatment can reduce primary and metastatic lesions probably by inducing apoptosis of tumor cells when they express the wild-type receptor. Defects in AR are the cause of androgen insensitivity syndrome partial (PAIS) [MIM:[http://omim.org/entry/312300 312300]]; also known as Reifenstein syndrome. PAIS is characterized by hypospadias, hypogonadism, gynecomastia, genital ambiguity, normal XY karyotype, and a pedigree pattern consistent with X-linked recessive inheritance. Some patients present azoospermia or severe oligospermia without other clinical manifestations. [[http://www.uniprot.org/uniprot/NCOA4_HUMAN NCOA4_HUMAN]] Defects in NCOA4 are a cause of thyroid papillary carcinoma (TPC) [MIM:[http://omim.org/entry/188550 188550]]. TPC is a common tumor of the thyroid that typically arises as an irregular, solid or cystic mass from otherwise normal thyroid tissue. Papillary carcinomas are malignant neoplasm characterized by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic epithelial cells. Note=A chromosomal aberration involving NCOA4 is found in thyroid papillary carcinomas. Inversion inv(10)(q11.2;q11.2) generates the RET/NCOA4 (PTC3) oncogene that has been found in sporadic and radiation-associated post-Chernobyl thyroid papillary carcinomas. | |||

[[http://www.uniprot.org/uniprot/ANDR_HUMAN ANDR_HUMAN]] Steroid hormone receptors are ligand-activated transcription factors that regulate eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Transcription factor activity is modulated by bound coactivator and corepressor proteins. Transcription activation is down-regulated by NR0B2. Activated, but not phosphorylated, by HIPK3 and ZIPK/DAPK3.<ref>PMID:14664718</ref><ref>PMID:18084323</ref><ref>PMID:19345326</ref><ref>PMID:20980437</ref><ref>PMID:15563469</ref><ref>PMID:17591767</ref><ref>PMID:17911242</ref> [[http://www.uniprot.org/uniprot/NCOA4_HUMAN NCOA4_HUMAN]] Enhances the androgen receptor transcriptional activity in prostate cancer cells.
