Genes affected

GBP6 (HGNC:25395): (guanylate binding protein family member 6) Guanylate-binding proteins, such as GBP6, are induced by interferon and hydrolyze GTP to both GDP and GMP (Olszewski et al., 2006 [PubMed 16689661]).[supplied by OMIM, Dec 2008]

Collection Method: clinical testing

The c.278T>C (p.L93P) alteration is located in exon 3 (coding exon 2) of the GBP6 gene. This alteration results from a T to C substitution at nucleotide position 278, causing the leucine (L) at amino acid position 93 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
