Genes affected

GBF1 (HGNC:4181): (golgi brefeldin A resistant guanine nucleotide exchange factor 1) This gene encodes a member of the Sec7 domain family. The encoded protein is a guanine nucleotide exchange factor that regulates the recruitment of proteins to membranes by mediating GDP to GTP exchange. The encoded protein is localized to the Golgi apparatus and plays a role in vesicular trafficking by activating ADP ribosylation factor 1. The encoded protein has also been identified as an important host factor for viral replication. Multiple transcript variants have been observed for this gene. [provided by RefSeq, Dec 2010]

The c.314C>T (p.T105I) alteration is located in exon 5 (coding exon 4) of the GBF1 gene. This alteration results from a C to T substitution at nucleotide position 314, causing the threonine (T) at amino acid position 105 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
