Genes affected
AR (HGNC:644): (androgen receptor) The androgen receptor gene is more than 90 kb long and codes for a protein that has 3 major functional domains: the N-terminal domain, DNA-binding domain, and androgen-binding domain. The protein functions as a steroid-hormone activated transcription factor. Upon binding the hormone ligand, the receptor dissociates from accessory proteins, translocates into the nucleus, dimerizes, and then stimulates transcription of androgen responsive genes. This gene contains 2 polymorphic trinucleotide repeat segments that encode polyglutamine and polyglycine tracts in the N-terminal transactivation domain of its protein. Expansion of the polyglutamine tract from the normal 9-34 repeats to the pathogenic 38-62 repeats causes spinal bulbar muscular atrophy (SBMA, also known as Kennedy's disease). Mutations in this gene are also associated with complete androgen insensitivity (CAIS). Alternative splicing results in multiple transcript variants encoding different isoforms.

Androgen resistance syndrome;C1839259:Kennedy disease Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | May 21, 2020 | This sequence change inserts 1 nucleotide in exon 1 of the AR mRNA (c.1440dupC), causing a frameshift at codon 481. This creates a premature translational stop signal (p.Tyr481Leufs*21) and is expected to result in an absent or disrupted protein product. For these reasons, this variant has been classified as Pathogenic. While this particular variant has not been reported in the literature, loss-of-function variants in AR are known to be pathogenic (PMID: 9463997, 20150575). - |
