Likely Benign for RASopathy. Applied ACMG criteria (verbatim):
BP7 BP4
Curation rationale (ClinGen, verbatim)
The c.1113T>C (p.Asp371=) is present in 7/1113684 European alleles (MAF 2.88e-05, 95% CI) gnomAD v2.1.1. Sixteen apparently unaffected parental samples involved in whole exome testing were observed with this variant supporting that this variant is likely benign; however, this evidence does not meet current scoring criteria for BS2 at this time (BS2 not met; SCV000515669.4). This variant is a synonymous (silent) variant at a nucleotide that is not highly conserved and is not predicted to impact splicing (BP7). Computational prediction tools and conservation analysis suggest that the p.Asp371= variant does not impact the protein (BP4). In summary, the clinical significance of the p.Asp371= variant is likely benign. RASopathy-specific ACMG/AMP criteria applied (PMID:29493581): BP7, BP4.

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.
