What condition is associated with FANCD2 p.Arg328= (c.984A>G)?

FANCD2 p.Arg328= (c.984A>G) is associated with Fanconi anemia (ClinVar).

How common is FANCD2 p.Arg328= (c.984A>G) in the general population?

FANCD2 p.Arg328= (c.984A>G) is very rare (popmax 0.00878%, sas) (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.
