Hi Everyone
I've enlisted the Medical Report feature offered by the at-home DNA analysis kit by SelfDecode. It offers you likelihoods and probabilities of certain health conditions based on your DNA code. I wanted to see what it had to say with my DNA data.
Ironically, my genetic risk of developing T1D was labeled as "typical". This is based on 1,047,920 genetic variants analyzed by SelfDecode.
The Medical Report feature offers a table of the key genetic variants that impacted your health score.
Here's a report I made up of the key factors that influenced my "typical" score. (Given that I already have T1D and that these genes have already had their influence, I'm interested to know more about how they work and why)
I've included a summary at the end where I categorize the gene's mentioned based on their potential influence on T1D development.
While I'm not entirely sure exactly what all this means just yet, I've been sitting with it for sometime and figure I'd put it out in the open to see if it can help anyone.
If you're interested in the SelfDecode DNA Kit, you can try it here.
Gene: N/A
SNP: rs11171739
Genotype: AG (1 risk allele)
Background on ERBB3:
Gene Function:
ERBB3 (Erb-B2 Receptor Tyrosine Kinase 3) is part of the epidermal growth factor receptor (EGFR) family. It plays a crucial role in cell signaling pathways that regulate cell proliferation, differentiation, and survival. In the immune system, ERBB3 signaling can influence immune cell development and function, which are crucial for maintaining immune homeostasis.
Relevance to T1D:
ERBB3's involvement in immune cell signaling suggests it could impact mechanisms underlying autoimmune diseases like T1D, where the body erroneously attacks insulin-producing cells in the pancreas.
SNP Information - rs11171739:
Location and Variation:
rs11171739 is a well-studied SNP located on chromosome 12q13 near the ERBB3 gene. It has been associated with various autoimmune diseases, including T1D, in multiple genetic studies.
Risk Association:
Research has shown that certain alleles at rs11171739 are linked with altered susceptibility to T1D. The presence of specific genotypes can influence the extent of ERBB3's impact on immunological pathways.
Genotype CC:
Association with T1D:
The CC genotype at rs11171739 might be linked with a specific level of risk for T1D, depending on the allele's prevalence and function in particular populations. In genetic studies, specific alleles (C or the alternative) influence ERBB3's expression or function.
Potential Mechanisms of Influence:
Immune Modulation: ERBB3 is involved in immune signaling pathways influencing how immune cells respond to self and non-self. Variants like rs11171739 could modulate these pathways, potentially affecting the balance between immune tolerance and autoimmunity.
T Cell Regulation: Given the gene's role in T cell function, changes due to the CC genotype might influence the regulatory T cell populations essential for preventing autoimmune attacks on pancreatic beta cells.
Cell Signaling Pathways: The CC genotype could lead to alterations in key signaling pathways that ERBB3 is involved in, such as those governing cytokine production and immune cell apoptosis. Changes in these pathways could contribute to an environment that fosters autoimmune activity, impacting the balance between cell death and cell survival in beta cells.
Interaction with Other Genes: It's important to consider that the impact of the CC genotype might not be isolated to ERBB3 alone. Genetic interactions—epistasis—can occur where variants in ERBB3 interact with other risk loci or immune-related genes. These interactions might amplify the overall effect on immune system regulation and autoimmunity risk.
Contextual Influence:
The effects of SNPs like rs11171739 are often modulated by larger genetic and environmental contexts. Factors such as the presence of other genetic variants, epigenetic modifications, and environmental triggers like infections can influence the manifestation of T1D. Thus, the risk associated with the CC genotype might also depend on these complex interactions.
