What condition is associated with FANCD2 p.Val473= (c.1419G>T)?

FANCD2 p.Val473= (c.1419G>T) is associated with Fanconi anemia (ClinVar).

How common is FANCD2 p.Val473= (c.1419G>T) in the general population?

FANCD2 p.Val473= (c.1419G>T) is ultra-rare (popmax 0.0339%, afr) (gnomAD).

How is Hereditary isolated aplastic anemia 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.
