Genes affected

ACKR1 (HGNC:4035): (atypical chemokine receptor 1 (Duffy blood group)) The protein encoded by this gene is a glycosylated membrane protein and a non-specific receptor for several chemokines. The encoded protein is the receptor for the human malarial parasites Plasmodium vivax and Plasmodium knowlesi. Polymorphisms in this gene are the basis of the Duffy blood group system. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Ambry Genetics

Sep 07, 2022

The c.735G>A (p.M245I) alteration is located in exon 1 (coding exon 1) of the ACKR1 gene. This alteration results from a G to A substitution at nucleotide position 735, causing the methionine (M) at amino acid position 245 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
