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.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.030859172).
BS2
High Homozygotes in GnomAd4 at 6 AR geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The c.1172A>G (p.K391R) alteration is located in exon 8 (coding exon 7) of the GBP1 gene. This alteration results from a A to G substitution at nucleotide position 1172, causing the lysine (K) at amino acid position 391 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
