Is ADAR p.Ser371Asn (c.1112G>A) pathogenic?

ADAR p.Ser371Asn (c.1112G>A) is classified Uncertain significance in ADAR (ClinVar, Multiple submitters, 2 submitters; last evaluated 2025-01-30). AlphaMissense: likely benign (0.0852); Absent from gnomAD v4.1; Associated with dyschromatosis symmetrica hereditaria.

What condition is associated with ADAR p.Ser371Asn (c.1112G>A)?

ADAR p.Ser371Asn (c.1112G>A) is associated with dyschromatosis symmetrica hereditaria, Aicardi-Goutieres syndrome 6 (ClinVar).

How common is ADAR p.Ser371Asn (c.1112G>A) in the general population?

ADAR p.Ser371Asn (c.1112G>A) is absent from gnomAD v4.1 (gnomAD).

How is Dyschromatosis symmetrica hereditaria inherited?

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

What do computational predictors say about ADAR p.Ser371Asn (c.1112G>A)?

AlphaMissense predicts likely benign (score 0.0852) — an in-silico prediction, not a clinical call.
