No pathogenic criterion marked as applied in the recorded assessment.
This variant exceeds the RASopathy VCEP BA1 threshold by a large margin. The filtering allele frequency threshold is 0.05%, while the observed allele frequency is 21.18080% in gnomAD v2.1 and 17.82506% in gnomAD v4.1; both values are far above the stand-alone benign threshold.
This variant exceeds the RASopathy VCEP BS1 population threshold. The filtering allele frequency threshold is 0.025%, whereas the observed allele frequency is 21.18080% in gnomAD v2.1 and 17.82506% in gnomAD v4.1, with many homozygotes in both datasets.
Computational evidence supports no meaningful molecular effect. SpliceAI predicts no significant splice impact with a maximum delta score of 0.01, and the REVEL score is 0.247, which is below the RASopathy VCEP benign threshold of 0.3.
