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.

The c.1154C>T (p.A385V) alteration is located in exon 7 (coding exon 6) of the GBP1 gene. This alteration results from a C to T substitution at nucleotide position 1154, causing the alanine (A) at amino acid position 385 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
