Is ADAR p.Pro615Ser (c.1843C>T) pathogenic?

ADAR p.Pro615Ser (c.1843C>T) is classified Uncertain significance in ADAR (ClinVar, Single submitter, 1 submitter; last evaluated 2025-08-20). AlphaMissense: ambiguous (0.5478); Very rare (popmax 8.47e-05%, nfe); Associated with dyschromatosis symmetrica hereditaria.

What condition is associated with ADAR p.Pro615Ser (c.1843C>T)?

ADAR p.Pro615Ser (c.1843C>T) is associated with dyschromatosis symmetrica hereditaria, Aicardi-Goutieres syndrome 6 (ClinVar).

How common is ADAR p.Pro615Ser (c.1843C>T) in the general population?

ADAR p.Pro615Ser (c.1843C>T) is very rare (popmax 8.47e-05%, nfe) (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.Pro615Ser (c.1843C>T)?

AlphaMissense predicts ambiguous (score 0.5478) — an in-silico prediction, not a clinical call.

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

Population frequency

Grpmax group 8.47e-05% European (non-Finnish) · 1/1,180,030 alleles

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.
