Polymorphism of the Fractalkine Receptor CX3CR1 and Systemic Sclerosis-associated Pulmonary Arterial Hypertension
Fractalkine (FKN) and its receptor CX3CR1 are critical mediators in the vascular and tissue damage of several chronic diseases, including systemic sclerosis (SSc) and pulmonary arterial hypertension (PAH). Interestingly, the V249I and T280M genetic polymorphism...

| description | Fractalkine (FKN) and its receptor CX3CR1 are critical mediators in the
vascular and tissue damage of several chronic diseases, including systemic
sclerosis (SSc) and pulmonary arterial hypertension (PAH). Interestingly, the V249I
and T280M genetic polymorphisms influence CX3CR1 expression and function. We
investigated whether these polymorphisms are associated with PAH secondary to
SSc. CX3CR1 genotypes were analyzed by PCR and sequencing in 76 patients with
limited SSc and 204 healthy controls. PAH was defined by colorDoppler echocardiography.
Homozygosity for 249II as well as the combined presence of 249II and 280MM were
significantly more frequent in patients with SSc compared to controls (17 vs 6%,
p = 0.0034 and 5 vs 1%, p = 0.0027, respectively). The 249I and 280M alleles were
associated with PAH (odd ratio [OR] 2.2, 95% confidence interval [CI] 1.01-4.75,
p = 0.028 and OR 7.37, 95%CI: 2.45-24.60, p = 0.0001, respectively). In conclusion,
the increased frequencies of 249I and 280M CX3CR1 alleles in a subgroup of
patients with SSc-associated PAH suggest a role for the fractalkine system in
the pathogenesis of this
condition. Further, the 249I allele might be associated with susceptibility to SSc. |
