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 17
Splicing
SpliceAI	—	not assessed · no allele here is in the release
Pangolin	Δ0.32	loss · gain 0.01 · not in the SpliceAI release · independent
Constraint at this position
Conservation	phyloP 7.7	GERP 1, phastCons 1
Overall
CADD	40.0	PHRED · no single calibrated threshold — expert panels disagree

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