ClinGen RASopathy Variant Curation Expert Panel RCV005253658 SCV005903440 benign RASopathy 2024-12-03 reviewed by expert panel curation The c.53-9G>A variant in PPP1CB is an intronic splicing variant located in intron 1 of PPP1CB. The filtering allele frequency in gnomAD v2 is 0.5284% in the African American population, which is higher than the ClinGen RASopathy VCEP threshold (>0.0005) for BA1, and therefore meets this criterion (BA1). In summary, this variant meets the criteria to be classified as benign for autosomal dominant RASopathy based on the ACMG/AMP criteria applied, as specified by the ClinGen RASopathy VCEP: BA1. (RASopathy VCEP specifications version 1.3; 12/3/2024)
