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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 18, 2024 | The c.1642C>G (p.P548A) alteration is located in exon 10 (coding exon 10) of the GTPBP1 gene. This alteration results from a C to G substitution at nucleotide position 1642, causing the proline (P) at amino acid position 548 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
