AlphaMissense: likely benign (0.187); Ultra-rare (popmax 0.0329%, mid); Associated with arrhythmogenic cardiomyopathy with wooly hair and keratoderma.

What condition is associated with DSP p.Arg572Gln (c.1715G>A)?

DSP p.Arg572Gln (c.1715G>A) is associated with arrhythmogenic cardiomyopathy with wooly hair and keratoderma, cardiomyopathy, arrhythmogenic right ventricular dysplasia 8 (ClinVar).

How common is DSP p.Arg572Gln (c.1715G>A) in the general population?

DSP p.Arg572Gln (c.1715G>A) is ultra-rare (popmax 0.0329%, mid) (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.Arg572Gln (c.1715G>A)?

AlphaMissense predicts likely benign (score 0.187) — an in-silico prediction, not a clinical call.

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.
