The ATM c.419A>T (p.(Asp140Val), p.(D140V)) variant has not been observed in somatic cancers in COSMIC and has not been reported in ClinVar.
clinvar ↗This variant is absent from gnomAD v2.1 and gnomAD v4.1, and its frequency of 0 is below the ATM PM2_Supporting threshold of less than or equal to 0.001%.
gnomad_v2 ↗ gnomad_v4 ↗ cspec ↗In an ATM supplementary functional dataset, p.(D140V) was classified as Functional with High confidence, but the available retrieved evidence does not provide the assay-level rescue details required to assign ATM PS3 or BS3 in this pass.
cspec ↗Computational evidence supports a damaging missense effect: REVEL is 0.815, above the ATM PP3 threshold of greater than 0.7333, BayesDel is 0.278827, and SpliceAI shows no significant splice impact with a maximum delta score of 0.06.
