Gene: PPP1CB (HGNC:9282)
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.

Evidence Code: PS1 — Original ACMG Summary
Same amino acid change as a previously established pathogenic variant regardless of nucleotide change.
Example: Val->Leu caused by either G>C or G>T in the same codon.
Caveat: Beware of changes that impact splicing rather than at the amino acid/protein level.

Evidence Code: PS3 — Original ACMG Summary
Well-established in vitro or in vivo functional studies supportive of a damaging effect on the gene or gene product.
Note: Functional studies that have been validated and shown to be reproducible and robust in a clinical diagnostic laboratory setting are considered the most well-established.
Gene: PPP1CB (HGNC:9282)
Evidence Code: PS4 — Original ACMG Summary
The prevalence of the variant in affected individuals is significantly increased compared to the prevalence in controls.
Note 1: Relative risk (RR) or odds ratio (OR), as obtained from case-control studies, is >5.0 and the confidence interval around the estimate of RR or OR does not include 1.0. See manuscript for detailed guidance.
Note 2: In instances of very rare variants where case-control studies may not reach statistical significance, the prior observation of the variant in multiple unrelated patients with the same phenotype, and its absence in controls, may be used as moderate level of evidence.

Gene: PPP1CB (HGNC:9282)
Evidence Code: PP3 — Original ACMG Summary
Multiple lines of computational evidence support a deleterious effect on the gene or gene product (conservation, evolutionary, splicing impact, etc.).
Caveat: As many in silico algorithms use the same or very similar input for their predictions, each algorithm should not be counted as an independent criterion. PP3 can be used only once in any evaluation of a variant.

Gene: PPP1CB (HGNC:9282)
Evidence Code: BS4 — Original ACMG Summary
Lack of segregation in affected members of a family.
Caveat: The presence of phenocopies for common phenotypes (i.e. cancer, epilepsy) can mimic lack of segregation among affected individuals. Also, families may have more than one pathogenic variant contributing to an autosomal dominant disorder, further confounding an apparent lack of segregation.
Gene: PPP1CB (HGNC:9282)

Gene: PPP1CB (HGNC:9282)
Evidence Code: BP1 — Original ACMG Summary
Missense variant in a gene for which primarily truncating variants are known to cause disease.
Gene: PPP1CB (HGNC:9282)
Evidence Code: BP1 — Supporting
Modification Type: Disease-specific
This rule has contraindications for use with RASopathies. Given the disease mechanism is gain-of-function for RASopathies, BP1 should be used for any truncating variant (nonsense, frameshift, affects canonical splice sites, initiation codon, entire gene or multi exon deletion) in genes without established LOF correlation to disease. See the supplemental material regarding dosage sensitivity information for each individual gene and potential association to disorders associated with LOF variants.

A synonymous variant for which splicing prediction algorithms predict no impact to the splice consensus sequence nor the creation of a new splice site AND the nucleotide is not highly conserved.
Gene: PPP1CB (HGNC:9282)
Evidence Code: BP7 — Supporting
Modification Type: General recommendation
A synonymous (silent) variant for which splicing prediction algorithms predict no impact to the splice consensus sequence nor the creation of a new splice site AND the nucleotide is not highly conserved. This rule is also applicable for intronic positions (except canonical splice sites) or non-coding variants and should be used in conjunction with BP4.
