Genes affected

MOB3C (HGNC:29800): (MOB kinase activator 3C) The protein encoded by this gene is similar to the yeast Mob1 protein. Yeast Mob1 binds Mps1p, a protein kinase essential for spindle pole body duplication and mitotic checkpoint regulation. Alternatively spliced transcript variants encoding distinct isoforms have been observed. [provided by RefSeq, Jul 2008]

MOB3C links:

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.

The c.400T>C (p.C134R) alteration is located in exon 2 (coding exon 2) of the MOB3C gene. This alteration results from a T to C substitution at nucleotide position 400, causing the cysteine (C) at amino acid position 134 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
