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 22 of 52
Splicing
SpliceAI	—	not assessed · substitutions only
Constraint at this position
Conservation	phyloP 11	GERP 2.4, phastCons 1

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

Population frequency

dbSNP / gnomAD

No gnomAD frequency available for this variant. This is missing data, not an absence: the variant may or may not be present in gnomAD. Rarity (ACMG PM2) and BA1/BS1 cannot be assessed for it.
