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.2545C>T variant is predicted to result in the amino acid substitution p.Pro849Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.023% 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. -
