This variant is absent from gnomAD v2.1 and gnomAD v4.1, with an observed population frequency of 0 in both datasets, which is below the PM2 rarity threshold of 0.1%.
gnomad_v2 ↗ gnomad_v4 ↗ cspec ↗3
This is a synonymous change, and SpliceAI predicts no significant splice impact with a maximum delta score of 0.01, which supports BP7 and argues against a predicted RNA effect.
