Genes affected

MAPK8IP3 (HGNC:6884): (mitogen-activated protein kinase 8 interacting protein 3) The protein encoded by this gene shares similarity with the product of Drosophila syd gene, required for the functional interaction of kinesin I with axonal cargo. Studies of the similar gene in mouse suggested that this protein may interact with, and regulate the activity of numerous protein kinases of the JNK signaling pathway, and thus function as a scaffold protein in neuronal cells. The C. elegans counterpart of this gene is found to regulate synaptic vesicle transport possibly by integrating JNK signaling and kinesin-1 transport. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Jul 2008]

The c.428A>G (p.Y143C) alteration is located in exon 2 (coding exon 2) of the MAPK8IP3 gene. This alteration results from a A to G substitution at nucleotide position 428, causing the tyrosine (Y) at amino acid position 143 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
