Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000211752 SCV000061618 pathogenic Cardio-facio-cutaneous syndrome 2012-06-26 criteria provided, single submitter clinical testing The Thr241Pro variant in BRAF has been reported in the literature in four indivi duals with clinical features of Cardio-facio-cutaneous syndrome, LEOPARD, or Cos tello syndrome (Nava 2007, Schulz 2008, Sarkozy 2009). This variant was reported to have occurred de novo in three of those individuals. Therefore, this variant meets our criteria to be classified as pathogenic.

Invitae RCV000654966 SCV000776876 pathogenic Rasopathy 2017-11-27 criteria provided, single submitter clinical testing This sequence change replaces threonine with proline at codon 241 of the BRAF protein (p.Thr241Pro). The threonine residue is highly conserved and there is a small physicochemical difference between threonine and proline. This variant is not present in population databases (ExAC no frequency). This variant has been reported to be de novo in individuals affected with cardio–facio–cutaneous syndrome (PMID: 17704260, 18042262). ClinVar contains an entry for this variant (Variation ID: 29807). Experimental studies have shown that this missense change p.Thr241Pro reduced amplitudes of synaptic responses in rat neurons (PMID: 28404629). A different missense substitution at this codon (p.The241Met) has been determined to be pathogenic (PMID: 19206169). This suggests that the threonine residue is critical for BRAF protein function and that other missense substitutions at this position may also be pathogenic. For these reasons, this variant has been classified as Pathogenic.
