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]

Aug 23, 2021

The c.124T>G (p.F42V) alteration is located in exon 1 (coding exon 1) of the GTPBP1 gene. This alteration results from a T to G substitution at nucleotide position 124, causing the phenylalanine (F) at amino acid position 42 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
