Is AR p.Lys837= (c.2511G>A) pathogenic?

AR p.Lys837= (c.2511G>A) is classified Likely benign in AR (ClinVar, Single submitter, 1 submitter; last evaluated 2023-11-04). Very rare (popmax 0.00652%, amr); Associated with Kennedy disease.

What condition is associated with AR p.Lys837= (c.2511G>A)?

AR p.Lys837= (c.2511G>A) is associated with Kennedy disease, androgen insensitivity syndrome (ClinVar).

How common is AR p.Lys837= (c.2511G>A) in the general population?

AR p.Lys837= (c.2511G>A) is very rare (popmax 0.00652%, amr) (gnomAD).

How is Kennedy disease inherited?

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

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
