The c.1433-19A>G in BRAF is an intronic variant located in intron 11. The minor allele frequency of this variant in gnomAD v4 is 0.2572% (3030/1178128) in the European (non-Finnish) population, which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen RASopathy Expert panel for autosomal dominant RASopathy variants (BA1). This variant is not predicted by SpliceAI to impact splicing. In addition, it occurs at a nucleotide that is not conserved (BP4, BP7). This variant has been identified in at least 2 patients with clinical features of a RASopathy (PS4_Supporting not met; GeneDx, Greenwood Genetics, Otto von Guericke University Magdeburg, internal data, GTR ID's: 26957, 1019; ClinVar SCV000207632.1, SCV000167210.14). However, this variant has been identified in a patient with an alternate molecular basis for disease (BP5; GeneDx internal data, GTR ID's: 26957; ClinVar SCV000167210.14). In summary, this variant meets criteria to be classified as benign for autosomal dominant RASopathies based on the ACMG/AMP criteria applied, as specified by the ClinGen RASopathy Variant Curation Expert Panel: BA1, BP4, BP5, BP7 (Specification Version 2.1, 9/17/2024)
