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.

The AR c.1403_1420dup18 variant is predicted to result in an in-frame duplication (p.Gly468_Gly473dup). To our knowledge, this variant has not been reported in the literature or in a large population database. However, the allele frequency of variant in gnomAD is not reliable due to the repetitive nature of the affected region. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
