NM_006206.5:c.1988C>T (p.Ala663Val) is a missense variant in exon 14 of PDGFRA, a receptor tyrosine kinase gene. This variant is absent from gnomAD v2.1 and v4.1 (0/1,607,834 alleles), meeting PM2 at supporting strength.1 In silico analysis yields conflicting predictions: REVEL score of 0.755 suggests a damaging effect, but BayesDel (0.21064) and SpliceAI (max delta 0.00) predict a benign/no-impact outcome. Multiple lines of computational evidence do not converge on pathogenicity; PP3 is not met.2 BayesDel and SpliceAI independently predict no deleterious effect, meeting BP4 at supporting benign strength.3 This variant is absent from ClinVar; no pathogenic or benign classification exists from any expert panel or clinical laboratory. PS1, PS5, PM5, PP5, and BP6 cannot be applied.4 No functional studies, de novo reports, case-control data, segregation data, or publications mentioning this specific variant were identified. PS2, PS3, PS4, PM6, PP1, PP4, BS2, BS3, BS4, BP2, and BP5 are not met.5 The variant is not located in a statistically significant mutational hotspot and no domain-level enrichment data support PM1. The gene-level PVS1 review does not provide robust evidence that PDGFRA disease is primarily caused by truncating variants; BP1 is not met. PVS1 is not applicable to this missense variant.6 PM2 (supporting pathogenic) and BP4 (supporting benign) are both met; the evidence is balanced and does not reach a classification threshold in either direction.7 Using the generic ACMG/AMP 2015 combination rules (Richards et al., PMID:25741868), one supporting pathogenic criterion (PM2) and one supporting benign criterion (BP4) result in a Variant of Uncertain Significance (VUS).8
