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]

The c.270C>A (p.F90L) alteration is located in exon 1 (coding exon 1) of the ACKR1 gene. This alteration results from a C to A substitution at nucleotide position 270, causing the phenylalanine (F) at amino acid position 90 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
