Is DSP p.Ser2861Phe (c.8582C>T) pathogenic?

DSP p.Ser2861Phe (c.8582C>T) is classified Likely benign in DSP (ClinVar, Single submitter, 1 submitter; last evaluated 2022-08-16). AlphaMissense: likely benign (0.2395); Very rare (popmax 0.00167%, amr); Associated with arrhythmogenic right ventricular dysplasia 8.

What condition is associated with DSP p.Ser2861Phe (c.8582C>T)?

DSP p.Ser2861Phe (c.8582C>T) is associated with arrhythmogenic right ventricular dysplasia 8, arrhythmogenic cardiomyopathy with wooly hair and keratoderma (ClinVar).

How common is DSP p.Ser2861Phe (c.8582C>T) in the general population?

DSP p.Ser2861Phe (c.8582C>T) is very rare (popmax 0.00167%, amr) (gnomAD).

What do computational predictors say about DSP p.Ser2861Phe (c.8582C>T)?

AlphaMissense predicts likely benign (score 0.2395) — an in-silico prediction, not a clinical call.

DSP p.Ser2861Phe

Q: How is Inherited isolated arrhythmogenic cardiomyopathy inherited?

Typically Autosomal dominant (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.
