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.251C>T (p.P84L) alteration is located in exon 3 (coding exon 2) of the GBP6 gene. This alteration results from a C to T substitution at nucleotide position 251, causing the proline (P) at amino acid position 84 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
