Is ATP7B p.Ile613= (c.1839C>T) pathogenic?

ATP7B p.Ile613= (c.1839C>T) is classified Likely benign in ATP7B (ClinVar, Multiple submitters, 8 submitters; last evaluated 2026-01-12). Ultra-rare (popmax 0.0217%, amr); Associated with Wilson disease.

What condition is associated with ATP7B p.Ile613= (c.1839C>T)?

ATP7B p.Ile613= (c.1839C>T) is associated with Wilson disease (ClinVar).

How common is ATP7B p.Ile613= (c.1839C>T) in the general population?

ATP7B p.Ile613= (c.1839C>T) is ultra-rare (popmax 0.0217%, amr) (gnomAD).

How is Wilson disease inherited?

Typically 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.
