What condition is associated with TERT p.His762= (c.2286C>T)?

TERT p.His762= (c.2286C>T) is associated with idiopathic pulmonary fibrosis, dyskeratosis congenita, autosomal dominant 2, dyskeratosis congenita (ClinVar).

How common is TERT p.His762= (c.2286C>T) in the general population?

TERT p.His762= (c.2286C>T) is ultra-rare (popmax 0.0231%, sas) (gnomAD).

How is Idiopathic pulmonary fibrosis inherited?

Typically Multigenic/multifactorial (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.
