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 haploinsufficient gene (ClinGen)
NMD	escapes	premature termination codon within the last 50 nt of the penultimate exon (15 of 16, 35 nt from its 3' end) — the truncated protein is likely expressed. PVS1 input, not an applied code
Splicing
SpliceAI	—	not assessed · substitutions only
Constraint at this position
Conservation	phyloP 0.6	GERP -2.4, phastCons 0.8

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