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.

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 766 of the AR protein (p.Ala766Thr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with complete androgen insensitivity syndrome (PMID: 1307250, 8723113, 9328206, 9856504, 10690872, 15531547, 15925895, 25248670, 25613104, 27899157). ClinVar contains an entry for this variant (Variation ID: 458363). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on AR protein function. Experimental studies have shown that this missense change affects AR function (PMID: 1307250, 9328206, 9856504, 10690872, 15531547). For these reasons, this variant has been classified as Pathogenic. -
