Genes affected

ART4 (HGNC:726): (ADP-ribosyltransferase 4 (inactive) (Dombrock blood group)) This gene encodes a protein that contains a mono-ADP-ribosylation (ART) motif. It is a member of the ADP-ribosyltransferase gene family but enzymatic activity has not been demonstrated experimentally. Antigens of the Dombrock blood group system are located on the gene product, which is glycosylphosphatidylinosotol-anchored to the erythrocyte membrane. Allelic variants, some of which lead to adverse transfusion reactions, are known. [provided by RefSeq, Jul 2008]

Ambry Genetics

Oct 16, 2023

The c.73T>C (p.W25R) alteration is located in exon 1 (coding exon 1) of the ART4 gene. This alteration results from a T to C substitution at nucleotide position 73, causing the tryptophan (W) at amino acid position 25 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
