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]

The KSR2 c.2440G>A variant is predicted to result in the amino acid substitution p.Asp814Asn. This variant was previously reported in one patient with severe early-onset obesity; however, no additional information was available to help clarify the pathogenicity of this variant (Pearce et al. 2013. PubMed ID: 24209692, reported as D843N). This variant is reported in 0.012% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
