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]

The c.1868C>T (p.S623F) alteration is located in exon 11 (coding exon 11) of the GTPBP1 gene. This alteration results from a C to T substitution at nucleotide position 1868, causing the serine (S) at amino acid position 623 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
