Is FANCD2 p.Pro806= (c.2418T>G) pathogenic?

FANCD2 p.Pro806= (c.2418T>G) is classified Conflicting classifications of pathogenicity in FANCD2 (ClinVar, Conflicting submitters, 4 submitters; last evaluated 2026-01-18). Ultra-rare (popmax 0.03%, amr); Associated with Fanconi anemia.

What condition is associated with FANCD2 p.Pro806= (c.2418T>G)?

FANCD2 p.Pro806= (c.2418T>G) is associated with Fanconi anemia, Fanconi anemia complementation group D2 (ClinVar).

How common is FANCD2 p.Pro806= (c.2418T>G) in the general population?

FANCD2 p.Pro806= (c.2418T>G) is ultra-rare (popmax 0.03%, amr) (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.
