Genes affected

GBP3 (HGNC:4184): (guanylate binding protein 3) This gene encodes a member of the guanylate-binding protein (GBP) family. GBPs specifically bind guanine nucleotides (GMP, GDP, and GTP) and contain two of the three consensus motifs found in typical GTP-binding proteins. The encoded protein interacts with a member of the germinal center kinase family. Multiple transcript variants encoding different isoforms have been found for this gene.

Collection Method: clinical testing

The c.931G>A (p.E311K) alteration is located in exon 7 (coding exon 6) of the GBP3 gene. This alteration results from a G to A substitution at nucleotide position 931, causing the glutamic acid (E) at amino acid position 311 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
