Is AR p.Ile915= (c.2745C>T) pathogenic?

AR p.Ile915= (c.2745C>T) is classified Likely benign in AR (ClinVar, Single submitter, 1 submitter; last evaluated 2023-03-20). Absent from gnomAD v4.1; Associated with Kennedy disease.

What condition is associated with AR p.Ile915= (c.2745C>T)?

AR p.Ile915= (c.2745C>T) is associated with Kennedy disease, androgen insensitivity syndrome (ClinVar).

How common is AR p.Ile915= (c.2745C>T) in the general population?

AR p.Ile915= (c.2745C>T) is absent from gnomAD v4.1 (gnomAD).

How is Kennedy disease inherited?

Typically X-linked recessive (Orphanet). A genetic counselor can assess individual risk for a family.
