Computational evidence
| Protein change | ||
| Missense predictors do not apply to this variant type; conservation carries the signal. | ||
| Consequence | nonsense (stop-gain) | predicted loss-of-function in a haploinsufficient gene (ClinGen) |

| NMD | predicted | premature termination codon in exon 4 of 31 |

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.
