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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.1015G>A (p.V339M) alteration is located in exon 6 (coding exon 6) of the GTPBP1 gene. This alteration results from a G to A substitution at nucleotide position 1015, causing the valine (V) at amino acid position 339 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
