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]
C12orf60 (HGNC:28726): (chromosome 12 open reading frame 60)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 18, 2024The c.739A>T (p.I247F) alteration is located in exon 2 (coding exon 2) of the ART4 gene. This alteration results from a A to T substitution at nucleotide position 739, causing the isoleucine (I) at amino acid position 247 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
