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]

RAF1 links:

MKRN2 (HGNC:7113): (makorin ring finger protein 2) This gene encodes a probable E3 ubiquitin ligase containing several zinc finger domains, that is a member of the makorin RING zinc-finger protein family. This gene overlaps the v-raf-1 murine leukemia viral oncogene homolog 1 (RAF1) gene in an antisense orientation and may have a co-regulatory function with RAF1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2012]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The RAF1 c.1688G>A; p.Arg563Gln variant (rs727504827), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 179378). This variant is found in the general population with an overall allele frequency of 0.002 % (5/251250 alleles) in the Genome Aggregation Database. Computational analyses predict that this variant is deleterious (REVEL: 0.777). Due to limited information, the clinical significance of this variant is uncertain at this time. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The Arg563Gln variant in SOS1 has now been identified by our laboratory in one a ffected individual and his reportedly unaffected mother. Computational predictio n tools and conservation analyses do not provide strong support for or against a n impact to the normal function of the protein. In summary, additional informati on is needed to assess the clinical significance of the Arg563Gln variant. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.R563Q variant (also known as c.1688G>A), located in coding exon 15 of the RAF1 gene, results from a G to A substitution at nucleotide position 1688. The arginine at codon 563 is replaced by glutamine, an amino acid with highly similar properties. This alteration has been reported in a cardiomyopathy cohort (Akinrinade O et al. J Cardiovasc Transl Res, 2023 Dec;16:1287-1302). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 563 of the RAF1 protein (p.Arg563Gln). This variant is present in population databases (rs727504827, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with RAF1-related conditions. ClinVar contains an entry for this variant (Variation ID: 179378). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt RAF1 protein function with a positive predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
