Genes affected

TRAPPC10 (HGNC:11868): (trafficking protein particle complex subunit 10) The protein encoded by this gene is a transmembrane protein found in the cis-Golgi complex. The encoded protein is part of the multisubunit transport protein particle (TRAPP) complex and may be involved in vesicular transport from the endoplasmic reticulum to the Golgi. Mutations in this gene could be responsible for the Unverricht-Lundborg type of progressive myoclonus epilepsy, or for autoimmune polyglandular disease type 1. [provided by RefSeq, Jul 2008]

The c.787G>A (p.G263R) alteration is located in exon 6 (coding exon 6) of the TRAPPC10 gene. This alteration results from a G to A substitution at nucleotide position 787, causing the glycine (G) at amino acid position 263 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
