AlphaMissense: likely pathogenic (0.9961); Absent from gnomAD v4.1; Associated with arrhythmogenic cardiomyopathy with wooly hair and keratoderma.

How common is DSP p.Ser597Pro (c.1789T>C) in the general population?

DSP p.Ser597Pro (c.1789T>C) is absent from gnomAD v4.1 (gnomAD).

How is Carvajal syndrome inherited?

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

What do computational predictors say about DSP p.Ser597Pro (c.1789T>C)?

AlphaMissense predicts likely pathogenic (score 0.9961) — an in-silico prediction, not a clinical call.
