Gene: SGCB (HGNC:10806)
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.
Gene: SGCB (HGNC:10806)
Evidence Code: PS1 — Strong
Modification Type: Disease-specific,General recommendation
For missense variants for which the amino acid change is the expected mechanism of disease, apply at Strong for 1 pathogenic or 2 likely pathogenic variants resulting in the same amino acid change. The likely pathogenic or pathogenic variant(s) must have been classified using LGMD VCEP specifications, and potential splice effects must be excluded for the missense variant under curation and the variant(s) resulting in the same amino acid change (SpliceAI score ≤0.10 or experimental evidence of normal splicing). PS1 can potentially be applied to multiple nucleotide changes at the same residue as long as the variant classification that determines the strength level does not depend on PS1 application.


For missense variants encoded by the first or last 3 nucleotides of an exon, PS1 should be considered only in the context of altered splicing (see below), unless a splice effect has been experimentally ruled out for the variant under curation and the variant(s) resulting in the same amino acid change. 


For variants for which the nucleotide change is the expected mechanism of disease (altered splicing), follow SVI Working Group recommendations (Walker et al. 2023; PMID: 37352859).

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.

Evidence Code: PS3 — Strong
Modification Type: Disease-specific,General recommendation
Variant-specific animal models are rare but may be assessed on a case-by-case basis and PS3 applied at a strength level that reflects how well the model recapitulates features observed in human patients. Apply PS3 at Strong for a variant-specific animal model that meets all of the following conditions, regardless of species: 




signs of myopathy or dystrophy are present in skeletal muscle 


an effect on gene or protein function is demonstrated (e.g., decreased protein expression, impaired membrane localization, or other functional abnormality)


behavioral signs of muscle weakness


progression over time




For any variant type, experimental evidence for altered splicing should be scored under PVS1 in accordance with the decision tree for RNA splicing assay results outlined in Walker et al. 2023 (PMID: 37352859).


Apply PS3 only once, for the piece of evidence that meets the highest possible strength level.

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: SGCB (HGNC:10806)
Evidence Code: PS4 — Strong
Modification Type: Clarification
Use without disease-specific modification if case-control studies are available. 
While case-control studies could potentially be considered for a few pathogenic variants with high minor allele frequency, the VCEP is unaware of any such studies being conducted for 
SGCB
. Any case-control study would require careful selection of an appropriate control population given the potential for late onset and mild disease.

Modification Type: Disease-specific,Strength
Apply if the Grpmax alternate allele frequency / upper bound of the 95% confidence interval (95% CI) of the Grpmax alternate allele frequency in gnomAD is <0.00009. 




If only 1 or 2 alternate alleles are reported in the Grpmax population, apply if the Grpmax alternate allele frequency is <0.00009. 


If at least 3 alternate alleles are reported in the Grpmax population, apply if the upper bound of the 95% CI of the Grpmax alternate allele frequency is <0.00009.




Grpmax refers to the gnomAD subpopulation with the highest alternate allele frequency. Use large, non-bottlenecked genetic ancestry groups for the Grpmax; avoid using the Amish, Ashkenazi Jewish, European Finnish, Remaining, or Middle Eastern (genome).


The upper bound of the 95% CI must be calculated using the exome or genome allele numbers and counts from gnomAD. Confidence interval tools, such as Confit-de-MAF (
https://www.genecalculators.net/confit-de-maf.html
), can be used.


When comparing different versions of gnomAD for the variant frequency, use the allele count from the version with the largest allele number. 


For larger deletions or duplications that may not be well represented in gnomAD (e.g., single- or multi-exon events), also confirm the variant is not common in gnomAD SVs, gnomAD CNVs, or the Database of Genomic Variants (DGV) (
https://dgv.tcag.ca/dgv/app/home
).

Apply only for missense variants for which the amino acid change is the expected mechanism of disease.
