Computational evidence

Protein change
Missense predictors do not apply to this variant type; conservation carries the signal.
Consequencenonsense (stop-gain)predicted loss-of-function
NMDescapespremature termination codon in the last exon (3 of 3) — the truncated protein is likely expressed. PVS1 input, not an applied code

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

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
