Genes affected

GTPBP1 (HGNC:4669): (GTP binding protein 1) This gene is upregulated by interferon-gamma and encodes a protein that is a member of the AGP11/GTPBP1 family of GTP-binding proteins. A structurally similar protein has been found in mouse, where disruption of the gene for that protein had no observable phenotype. [provided by RefSeq, Jul 2008]

Ambry Genetics

Apr 22, 2024

The c.1807G>A (p.D603N) alteration is located in exon 11 (coding exon 11) of the GTPBP1 gene. This alteration results from a G to A substitution at nucleotide position 1807, causing the aspartic acid (D) at amino acid position 603 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
