The recorded framework is ClinGen BRAF VCEP v2.3.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.
The applied criteria and their strengths are shown as assessed under the stated framework.
No pathogenic criterion marked as applied in the recorded assessment.
The variant has a gnomAD filtering allele frequency (grpmax FAF) of 0.1388% in v2.1 and 0.1350% in v4.1, exceeding the CSPEC RASopathy VCEP BA1 threshold of ≥0.05%. This is consistent with a benign population polymorphism for a dominant RASopathy disorder.
The variant has a gnomAD filtering allele frequency (grpmax FAF) of 0.1388% in v2.1 and 0.1350% in v4.1, exceeding the CSPEC RASopathy VCEP BS1 threshold of ≥0.025%. The observed frequency in the general population is inconsistent with a highly penetrant dominant RASopathy disorder.
Homozygotes for this variant are observed in gnomAD (1 in v2.1, 2 in v4.1). For a dominant disorder such as RASopathy with full penetrance expected at an early age, observation of homozygous healthy individuals in population databases constitutes strong evidence for a benign classification.
CSPEC RASopathy VCEP BP4 for splicing variants requires predicted outcome to be negligible or not matching disease mechanism. SpliceAI predicts no significant splice impact for this synonymous variant (max delta score 0.01), satisfying the BP4 criteria for a negligible predicted splicing outcome.
Expert panel ClinGen RASopathy Variant Curation Expert Panel classified as Benign.
This is a synonymous (silent) variant (p.Gln356=) for which SpliceAI predicts no impact to the splice consensus sequence nor creation of a new splice site (max delta 0.01). The nucleotide is not in a known highly conserved functional element within the critical domains defined by the VCEP. BP7 is applied in conjunction with BP4 per CSPEC guidance.
ClinGen RASopathy Expert Panel Specifications to the ACMG/AMP Variant Interpretation Guidelines for BRAF Version 2.3.0 v2.3.0 criteria-combination framework: matched Rule17 (1 Benign.Stand Alone) with applied criteria: BA1 stand-alone benign, BS1 strong benign, BS2 strong benign, BP4 supporting benign, BP6 supporting benign, BP7 supporting benign; maps to Benign.

The variant NM_001354609.1:c.1068A>G (p.Gln356=) is a synonymous substitution in BRAF exon 8, outside the critical functional domains defined by the ClinGen RASopathy VCEP.
This variant is present in gnomAD v2.1 at an allele frequency of 0.02546% (72/282,848 alleles, 1 homozygote) with a grpmax filtering allele frequency of 0.1388%, and in gnomAD v4.1 at 0.01394% (225/1,614,110 alleles, 2 homozygotes) with a grpmax FAF of 0.1350%.
BA1 is met at stand-alone benign strength: the gnomAD grpmax FAF of 0.1388% (v2.1) and 0.1350% (v4.1) exceeds the CSPEC RASopathy VCEP threshold of ≥0.05%.
BS1 is met at strong benign strength: the gnomAD grpmax FAF exceeds the CSPEC RASopathy VCEP threshold of ≥0.025%.
BS2 is met at strong level: homozygous individuals are observed in gnomAD (1 in v2.1, 2 in v4.1), which is inconsistent with a highly penetrant autosomal dominant RASopathy disorder.
BP4 is met at supporting benign strength: SpliceAI predicts no significant splice impact (max delta 0.01), satisfying the VCEP BP4 criterion for negligible predicted splicing outcome.
BP7 is met at supporting benign strength: the variant is synonymous (p.Gln356=) with no predicted splice impact (SpliceAI delta 0.01), applied in conjunction with BP4.
The ClinGen RASopathy Variant Curation Expert Panel has classified this variant as Benign (ClinVar Variation ID 44788), applying criteria BA1, BS1, BP4, and BP7, consistent with this independent assessment.
Under the CSPEC RASopathy VCEP v2.3.0 classification framework Rule 17, BA1 alone (stand-alone benign) is sufficient for a Benign classification. Additionally, BS1 (strong) and BS2 (strong) satisfy Rule 16 (≥2 strong benign criteria). The variant is classified as Benign.
