What condition is associated with WT1 p.Asp347= (c.1041T>C)?

WT1 p.Asp347= (c.1041T>C) is associated with Denys-Drash syndrome, Frasier syndrome, Wilms tumor 1 (ClinVar).

How common is WT1 p.Asp347= (c.1041T>C) in the general population?

WT1 p.Asp347= (c.1041T>C) is very rare (popmax 0.00167%, amr) (gnomAD).

How is Denys-Drash syndrome 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.
