What condition is associated with KIT p.Val845= (c.2535A>G)?

KIT p.Val845= (c.2535A>G) is associated with gastrointestinal stromal tumor, hereditary neoplastic syndrome (ClinVar).

How common is KIT p.Val845= (c.2535A>G) in the general population?

KIT p.Val845= (c.2535A>G) is ultra-rare (popmax 0.0165%, mid) (gnomAD).

How is Gastrointestinal stromal tumor inherited?

Typically Autosomal dominant, Not applicable (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.
