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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.401 is higher than 0.05.
