Computational evidence
| Protein change | ||
| Missense predictors do not apply to this variant type; conservation/SpliceAI carries the signal. | ||
| Consequence | nonsense (stop-gain) | predicted loss-of-function in a LoF-intolerant gene |
|---|---|---|
| NMD | predicted | premature termination codon in exon 3 of 13 |
| Splicing | ||
| SpliceAI | Δ0.28 | acceptor gain · deltas |
| Pangolin | Δ0.28 | gain · loss 0.00 · agrees with SpliceAI · independent |
| Constraint at this position | ||
| Conservation | phyloP 5.5 | GERP 2, phastCons 1 |
| Overall | ||
| CADD | 38.0 | 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 |
|---|---|---|
| East Asiangrpmax | 0.00446% | 22,439 |
| Admixed American | 0.00167% | 60,012 |
| European (non-Finnish) | 0.000254% | 393,342 |
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.
