Characterization of a novel inherited splice-site variant in MAPK8IP3 expands the genetic and phenotypic spectrum of neurodevelopmental disorders
{{output}}
Background: The MAPK8IP3 gene encodes JIP3, a kinesin-1 adapter protein crucial for axonal transport and JNK signaling pathway regulation. This gene exhibits extreme intolerance to loss-of-function variants. Heterozygous pathogen... ...
