Computational evidence

Protein change
Missense predictors do not apply to this variant type; conservation carries the signal.
Consequence	frameshift	predicted loss-of-function in a LoF-intolerant gene
NMD	predicted	premature termination codon in exon 27 of 52
Splicing
SpliceAI	—	not assessed · substitutions only
Constraint at this position
Conservation	phyloP 11	GERP 2.7, phastCons 1

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