Genes affected

CX3CR1 (HGNC:2558): (C-X3-C motif chemokine receptor 1) Fractalkine is a transmembrane protein and chemokine involved in the adhesion and migration of leukocytes. The protein encoded by this gene is a receptor for fractalkine. The encoded protein also is a coreceptor for HIV-1, and some variations in this gene lead to increased susceptibility to HIV-1 infection and rapid progression to AIDS. Four transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jan 2010]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=5.266823E-6).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.658 is higher than 0.05.
