Genes affected

MAP2K7 (HGNC:6847): (mitogen-activated protein kinase kinase 7) The protein encoded by this gene is a dual specificity protein kinase that belongs to the MAP kinase kinase family. This kinase specifically activates MAPK8/JNK1 and MAPK9/JNK2, and this kinase itself is phosphorylated and activated by MAP kinase kinase kinases including MAP3K1/MEKK1, MAP3K2/MEKK2,MAP3K3/MEKK5, and MAP4K2/GCK. This kinase is involved in the signal transduction mediating the cell responses to proinflammatory cytokines, and environmental stresses. Alternative splicing results in multiple transcript variants.

The c.649C>T (p.R217C) alteration is located in exon 6 (coding exon 6) of the MAP2K7 gene. This alteration results from a C to T substitution at nucleotide position 649, causing the arginine (R) at amino acid position 217 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
