Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4BP7

This summary comes from the ClinGen Evidence Repository: Computational prediction tools and conservation analysis suggest that the c.680+6T>C variant in the RAF1 gene does not impact the protein (BP4). This is an intronic variant at a nucleotide that is not highly conserved and is not predicted to impact splicing (BP7). In addition, this variant is observed in many individuals in the normal population suggesting it is an unlikely cause of a RASopathy (BS1 not met). In summary, this variant meets criteria to be classified as likely benign. RASopathy-specific ACMG/AMP criteria applied (PMID:29493581): BP4, BP7.

Genes affected

RAF1 (HGNC:9829): (Raf-1 proto-oncogene, serine/threonine kinase) This gene is the cellular homolog of viral raf gene (v-raf). The encoded protein is a MAP kinase kinase kinase (MAP3K), which functions downstream of the Ras family of membrane associated GTPases to which it binds directly. Once activated, the cellular RAF1 protein can phosphorylate to activate the dual specificity protein kinases MEK1 and MEK2, which in turn phosphorylate to activate the serine/threonine specific protein kinases, ERK1 and ERK2. Activated ERKs are pleiotropic effectors of cell physiology and play an important role in the control of gene expression involved in the cell division cycle, apoptosis, cell differentiation and cell migration. Mutations in this gene are associated with Noonan syndrome 5 and LEOPARD syndrome 2. [provided by RefSeq, Jul 2008]
