BACKGROUND: Microglial activation is considered to assume a role in the pathogenesis of Amyotrophic Lateral Sclerosis (ALS). To date, the relationship between ALS and the rs3865444 polymorphism of the cluster of differentiation 33 (CD33) has not been explored. The current report aimed to investigate the potential connection between CD33 rs3865444 and ALS.
METHODS: Patients diagnosed with sporadic ALS according to the revised El Escorial criteria, as well as age and sex matched community controls, were enrolled. Two evenly numbered, age and sex matched groups of 155 participants each were genotyped.
RESULTS: No association was found between rs3865444 and ALS [log-additive odds ratio (OR) = 0.83 (0.57, 1.22), over-dominant OR = 0.86 (0.55, 1.36), recessive OR = 0.73 (0.25, 2.17), dominant OR = 0.82 (0.52, 1.29), co-dominant OR1 = 0.68 (0.23, 2.05) and co-dominant OR2 = 0.84 (0.53, 1.33)]. Moreover, no relationship was established between rs3865444 and the age of ALS onset based on both unadjusted and sex adjusted Cox-proportional hazards models. Finally, no association between rs3865444 and ALS was found in subgroup analyses based on the site of ALS onset (bulbar or spinal) and sex.
CONCLUSIONS: The current analysis is the first to report that rs3865444 is not linked to ALS. Larger multi-racial studies are required to confirm these findings.
