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 GeneticsApr 04, 2023The c.1111G>A (p.E371K) alteration is located in exon 7 (coding exon 7) of the GTPBP1 gene. This alteration results from a G to A substitution at nucleotide position 1111, causing the glutamic acid (E) at amino acid position 371 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
