What condition is associated with CSF2RA p.Thr119= (c.357C>T)?

CSF2RA p.Thr119= (c.357C>T) is associated with surfactant metabolism dysfunction, pulmonary, 4 (ClinVar).

How common is CSF2RA p.Thr119= (c.357C>T) in the general population?

CSF2RA p.Thr119= (c.357C>T) is very rare (popmax 0.000254%, nfe) (gnomAD).

How is Hereditary pulmonary alveolar proteinosis inherited?

Typically 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.
