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]
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]

Variant classified as Uncertain Significance - Favor Benign. The c.1537-13G>A va riant in RAF1 has not been previously reported in individuals with clinical feat ures of a RASopathy, but has been identified in 6/10324 African chromosomes by t he Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). This var iant is located in the 3' splice region. Computational tools do not suggest an i mpact to splicing. However, this information is not predictive enough to rule ou t pathogenicity. In summary, while the clinical significance of the c.1537-13G>A variant is uncertain, these data suggest that it is more likely to be benign. -
