Is MSH6 p.Arg511= (c.1533G>A) pathogenic?

MSH6 p.Arg511= (c.1533G>A) is classified Benign/Likely benign in MSH6 (ClinVar, Multiple submitters, 3 submitters; last evaluated 2026-01-20). Absent from gnomAD v4.1; Associated with Lynch syndrome 5.

What condition is associated with MSH6 p.Arg511= (c.1533G>A)?

MSH6 p.Arg511= (c.1533G>A) is associated with Lynch syndrome 5, hereditary neoplastic syndrome (ClinVar).

How common is MSH6 p.Arg511= (c.1533G>A) in the general population?

MSH6 p.Arg511= (c.1533G>A) is absent from gnomAD v4.1 (gnomAD).

How is Lynch syndrome inherited?

Typically Autosomal dominant (Orphanet). A genetic counselor can assess individual risk for a family.
