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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.725G>A (p.R242H) alteration is located in exon 6 (coding exon 5) of the GBP3 gene. This alteration results from a G to A substitution at nucleotide position 725, causing the arginine (R) at amino acid position 242 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
