Genes affected

JAKMIP2 (HGNC:29067): (janus kinase and microtubule interacting protein 2) The protein encoded by this gene is reported to be a component of the Golgi matrix. It may act as a golgin protein by negatively regulating transit of secretory cargo and by acting as a structural scaffold of the Golgi. Alternative splicing results in multiple transcript variants.

The c.1320C>G (p.D440E) alteration is located in exon 9 (coding exon 8) of the JAKMIP2 gene. This alteration results from a C to G substitution at nucleotide position 1320, causing the aspartic acid (D) at amino acid position 440 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
