Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2 PP3_Strong

The NM_002053.3(GBP1):​c.1294G>T​(p.Gly432Cys) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,662 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G432D) has been classified as Uncertain significance.

• Frequency:

• Consequence: GBP1 NM_002053.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 4.85

Genes affected

GBP1 (HGNC:4182): (guanylate binding protein 1) Guanylate binding protein expression is induced by interferon. Guanylate binding proteins are characterized by their ability to specifically bind guanine nucleotides (GMP, GDP, and GTP) and are distinguished from the GTP-binding proteins by the presence of 2 binding motifs rather than 3.
