Gene: GP1BA (HGNC:4439)
Evidence Code: PVS1 — Original ACMG Summary
Null variant (nonsense, frameshift, canonical +/−1 or 2 splice sites, initiation codon, single or multi-exon deletion) in a gene where loss of function (LOF) is a known mechanism of disease.
Caveats:
 • Beware of genes where LOF is not a known disease mechanism (e.g. GFAP, MYH7).
 • Use caution interpreting LOF variants at the extreme 3’ end of a gene.
 • Use caution with splice variants that are predicted to lead to exon skipping but leave the remainder of the protein intact.
 • Use caution in the presence of multiple transcripts.
