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]

KSR2-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesMar 25, 2024The KSR2 c.2720G>T variant is predicted to result in the amino acid substitution p.Arg907Leu. This variant was reported in one individual with severe obesity (reported as p.Arg936Leu in Figure 1, Pearce et al. 2013. PubMed ID: 24209692). This variant is reported in 0.0027% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant could be pathogenic. However, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
