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]

ACKR1 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0016954243).
• BP6: Variant 1-159205737-G-A is Benign according to our data. Variant chr1-159205737-G-A is described in ClinVar as [Benign]. Clinvar id is 3056036.Status of the report is no_assertion_criteria_provided, 0 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.17 is higher than 0.05.
