ClinGen expert panel — RASopathy VCEP
Uncertain Significance for RASopathy. Applied ACMG criteria (verbatim):
PP2
Curation rationale (ClinGen, verbatim)
The c.170C>T (p.Ser57Phe) variant in SHOC2 was present in 0.0055% (5/35376 CI 95%) of Latino alleles in gnomAD v2.1.1 (BS1 not met; PMID: 29493581). It has been identified in healthy individuals without clinical features of a RASopathy, but this information does not meet the current criteria to apply BS2 (Ambry Genetics internal data, Baylor Genetics internal data). The variant is located in SHOC2, which has been defined by the ClinGen RASopathy Expert Panel as a gene with a low rate of benign missense variants and pathogenic missense variants are common (PP2; PMID: 29493581). In summary, the clinical significance of the p.Ser57Phe variant is uncertain. RASopathy-specific ACMG/AMP criteria applied (PMID:29493581): PP2.

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
