Genes affected
MKNK1 (HGNC:7110): (MAPK interacting serine/threonine kinase 1) This gene encodes a Ser/Thr protein kinase that interacts with, and is activated by ERK1 and p38 mitogen-activated protein kinases, and thus may play a role in the response to environmental stress and cytokines. This kinase may also regulate transcription by phosphorylating eIF4E via interaction with the C-terminal region of eIF4G. Alternatively spliced transcript variants have been noted for this gene.

MKNK1-AS1 (HGNC:44129): (MKNK1 antisense RNA 1)

The c.1052T>C (p.I351T) alteration is located in exon 12 (coding exon 11) of the MKNK1 gene. This alteration results from a T to C substitution at nucleotide position 1052, causing the isoleucine (I) at amino acid position 351 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
