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]

GTPBP1 Gene-Disease associations (from GenCC):

neurodevelopmental disorder with characteristic facial and ectodermal features and tetraparesis 1
Inheritance: AR Classification: MODERATE Submitted by: G2P
