Is SLX4 p.Ser780= (c.2340T>C) pathogenic?

SLX4 p.Ser780= (c.2340T>C) is classified Likely benign in SLX4 (ClinVar, Single submitter, 1 submitter; last evaluated 2022-05-21). Very rare (popmax 0.000593%, nfe); Associated with Fanconi anemia.

What condition is associated with SLX4 p.Ser780= (c.2340T>C)?

SLX4 p.Ser780= (c.2340T>C) is associated with Fanconi anemia (ClinVar).

How common is SLX4 p.Ser780= (c.2340T>C) in the general population?

SLX4 p.Ser780= (c.2340T>C) is very rare (popmax 0.000593%, nfe) (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.
