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 missense variant c.401G>A (p.Arg134His) in MAPK8IP3 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.Arg134His variant is reported with allele frequency 0.0008% in gnomAD exomes and novel in 1000 Genomes. The amino acid Arg at position 134 is changed to a His changing protein sequence and it might alter its composition and physico-chemical properties. The amino acid change p.Arg134His in MAPK8IP3 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance . -
