Genes affected
KSR2 (HGNC:18610): (kinase suppressor of ras 2) Predicted to enable MAP-kinase scaffold activity; mitogen-activated protein kinase kinase binding activity; and protein kinase activity. Predicted to be involved in Ras protein signal transduction; calcium-mediated signaling; and positive regulation of cold-induced thermogenesis. Predicted to act upstream of or within positive regulation of MAPK cascade. Predicted to be active in cytosol and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Review Status: no assertion criteria provided
Collection Method: clinical testing

The KSR2 c.2440G>C variant is predicted to result in the amino acid substitution p.Asp814His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.00092% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/12-117914324-C-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
