Genes affected

TRAPPC9 (HGNC:30832): (trafficking protein particle complex subunit 9) This gene encodes a protein that likely plays a role in NF-kappa-B signaling. Mutations in this gene have been associated with autosomal-recessive cognitive disability. Alternatively spliced transcript variants have been described.[provided by RefSeq, Feb 2010]
