This variant is absent from gnomAD v2.1 and gnomAD v4.1, which is below the ATM PM2_Supporting threshold of 0.001% in gnomAD v4.

An ATM supplementary functional dataset classified this variant as non-functional, but the available evidence does not document the ATM VCEP-required rescue assay endpoints needed to apply PS3 or BS3.
cspec ↗4
In silico evidence supports a deleterious missense effect because REVEL is 0.753, which is above the ATM PP3 threshold of 0.7333, while SpliceAI predicts no meaningful splice impact with a maximum delta score of 0.02.
