Computational evidence

Protein change
Missense predictors do not apply to this variant type; conservation carries the signal.

Predicted loss-of-function is descriptive, not an applied PVS1 code.

gnomAD v4.1 · exomes + genomes

Absent from gnomAD v4.1. Not observed in any sequenced alleles — a rarity signal (ACMG PM2-supporting), not evidence of pathogenicity on its own.
