Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_002053.3(GBP1):ā€‹c.1294G>Cā€‹(p.Gly432Arg) variant causes a missense change. The variant allele was found at a frequency of 0.0000239 in 1,461,662 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G432D) has been classified as Uncertain significance.

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.

Collection Method: clinical testing

The c.1294G>C (p.G432R) alteration is located in exon 8 (coding exon 7) of the GBP1 gene. This alteration results from a G to C substitution at nucleotide position 1294, causing the glycine (G) at amino acid position 432 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
