Lta, or Lymphotoxin-α, is a gene encoding a protein that has implications in various biological processes and diseases. It is associated with the regulation of the immune response and has been linked to pathways related to inflammation and cancer development [1,2]. Lta gene polymorphisms may influence an individual's susceptibility to certain diseases, making it an important gene for genetic studies.

In terms of disease associations, specific Lta gene polymorphisms, such as rs2239704, are inversely associated with the risk of cancer, while rs1041981 polymorphism shows a negative association with cancer risk in Asians. Additionally, rs909253 polymorphism is a risk factor for HCC in the Caucasian population [1]. Moreover, a haplotype within the Lta gene (CTTAC haploblock) is associated with protection towards periodontitis in Italian adults [2].

In conclusion, Lta is a gene with significant implications in disease susceptibility. Studies on Lta gene polymorphisms have provided insights into how genetic variations can influence an individual's risk of developing cancer and periodontal disease. Understanding the role of Lta through genetic models can offer valuable information for disease prevention and treatment strategies related to these conditions.
