Is DSP p.Gln51= (c.153G>A) pathogenic?

DSP p.Gln51= (c.153G>A) is classified Likely benign in DSP (ClinVar, Multiple submitters, 2 submitters; last evaluated 2022-10-09). Very rare (popmax 0.000519%, nfe); Associated with arrhythmogenic cardiomyopathy with wooly hair and keratoderma.

How common is DSP p.Gln51= (c.153G>A) in the general population?

DSP p.Gln51= (c.153G>A) is very rare (popmax 0.000519%, nfe) (gnomAD).

How is Carvajal syndrome inherited?

Typically Autosomal dominant, Autosomal recessive (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.
