Computational evidence
| Protein change | ||
| Missense predictors do not apply to this variant type; conservation carries the signal. | ||
| Consequence | frameshift | predicted loss-of-function |
|---|---|---|
| NMD | escapes | premature termination codon in the last exon (8 of 8) — the truncated protein is likely expressed. PVS1 input, not an applied code |

| CADD | 19.12 | PHRED · no single calibrated threshold — expert panels disagree |
Predicted loss-of-function is descriptive, not an applied PVS1 code.
Population frequency
| Ancestry group | Frequency | 1 in |
|---|---|---|
| European (non-Finnish)grpmax | 0.00822% | 12,164 |
| Remaining individualsnot grpmax-eligible | 0.00801% | 12,479 |
| African / African-American | 0.00133% | 74,940 |
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.
