Variant summary: BRAF c.1783T>C (p.Phe595Leu) results in a non-conservative amino acid change located in the Protein kinase domain (IPR000719) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251240 control chromosomes (gnomAD). c.1783T>C has been reported in the literature in individuals affected with Cardiofaciocutaneous Syndrome (Ciara_2015, Matalon_2021), and in one case the de novo occurrence of the variant was confirmed. In addition two equivalent missense variants (c.1785T>A (p.F595L) and c.1785T>G (p.F595L)) have also been reported in patients affected with Cardio-facio-cutaneous syndrome (HGMD). These data indicate that the variant is likely associated with disease. Multiple publications reported experimental evidence evaluating an impact on protein function, and demonstrated that the variant results in low to intermediate Braf kinase activity, which works cooperatively with Ras leading to increased MEK/ERK signaling (Kordes_2016, Yao_2017, Ng_2018). Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant in the germline state to ClinVar after 2014, and classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.

This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 595 of the BRAF protein (p.Phe595Leu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with cardio-facio-cutaneous (CFC) syndrome (PMID: 16439621, 18042262, 19206169, 20186801, 21871821, 22495831, 23093928, 25463315, 29084544). In at least one individual the variant was observed to be de novo. This variant is also known as F594L. ClinVar contains an entry for this variant (Variation ID: 202193). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is expected to disrupt BRAF function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects BRAF function (PMID: 26582644). For these reasons, this variant has been classified as Pathogenic. (less)

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
