Classification rationale
1

The STK11 c.22C>G (p.Gln8Glu) variant has been reported in ClinVar as uncertain significance by five clinical laboratory submissions.

2

This variant is very rare in population databases, with AF 4.6322e-06 in gnomAD v2.1 and AF 2.50785e-06 in gnomAD v4.1, supporting rarity but not a benign frequency threshold.
