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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 13, 2022 | The c.356T>C (p.F119S) alteration is located in exon 2 (coding exon 1) of the CX3CR1 gene. This alteration results from a T to C substitution at nucleotide position 356, causing the phenylalanine (F) at amino acid position 119 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
