Imagine that the genes involved in Alzheimer’s disease are doing a complex, synchronized dance. In this study, scientists focused on one particular gene called ABCA7 and its relationship to Alzheimer’s disease risk in the southern Chinese population. They examined 21 different genetic variations within ABCA7 and found that two, known as rs3764650 and rs4147929, were associated with a higher risk of developing Alzheimer’s disease. These variations were particularly risky for individuals who carried a specific genetic marker called APOE ε4. It’s like a dance floor where certain moves lead to a higher chance of developing Alzheimer’s. More research with larger sample sizes will be needed to confirm these findings and unravel the intricacies of these genetic interactions.
ObjectiveThe study aimed to clarify the association of the 21 single nucleotide polymorphisms (SNPs) with Alzheimer’s disease (AD) in the population of southern China.MethodsA case-control study was conducted with a total sample size of 490 subjects (246 patients with AD and 244 age- and gender-matched healthy controls) enrolled in this study. Twenty-one selected SNPs were detected using SNaPshot assay and polymerase chain reaction (PCR) technique. Then, we assessed how these SNPs correlated with AD susceptibility.ResultsThe results showed that rs3764650 of ABCA7 was closely correlated with risen AD morbidity in the allele [P = 0.010, odds ratio (OR) = 1.43, 95% confidence interval (CI) 1.09–1.89], dominant (P = 0.004, OR = 1.71, 95% CI 1.19–2.46), and additive (P = 0.012, OR = 1.42, 95% CI 1.08–1.86) models. However, rs4147929 of ABCA7 was related to higher AD risk in the allele (P = 0.006, OR = 1.45, 95% CI 1.11–1.89), dominant (P = 0.012, OR = 1.59, 95% CI 1.11–2.27), and additive (P = 0.010, OR = 1.40, 95% CI 1.08–1.81) models. In addition, the frequencies of the G-allele at rs3764650 (P = 0.030) and the A-allele at rs4147929 (P = 0.001) in AD were statistically higher in APOE ε4 carriers in comparison to non-carriers.ConclusionThis study demonstrated that the G-allele at rs3764650 and the A-allele at rs4147929 appeared at higher risk for developing AD, particularly in APOE ε4 carriers. Moreover, it was observed that rs3764650 and rs4147929 of ABCA7 were linked to AD. More in-depth research with a relatively large sample is needed to make the results more convincing.
