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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 30, 2024The c.889A>G (p.T297A) alteration is located in exon 7 (coding exon 6) of the GBP3 gene. This alteration results from a A to G substitution at nucleotide position 889, causing the threonine (T) at amino acid position 297 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
