IGIP rs156092: What Your Genotype Means
The rs156092 variant is a genetic locus located within the IGIP gene. Recent research has identified this variant as a lead locus associated with Alzheimer's disease and related dementias, as well as changes in hippocampal volume.
What each genotype means
Typical genetic profile
This genotype is the most common form observed in the general population. Research identifies this locus as a novel candidate associated with Alzheimer's disease risk and hippocampal volume, though the specific biological mechanism remains unknown.
This is the most frequent genotype observed in most global populations.
Associated risk variant
Carrying this genotype has been statistically associated with Alzheimer's disease risk and variations in hippocampal volume in large-scale studies. Because this is a complex trait, this result does not provide a diagnosis and should be viewed as one of many factors influencing brain health.
This genotype is considered rare in the general population.

What is the rs156092 Variant?
The rs156092 variant is a single nucleotide polymorphism (SNP) located within the IGIP gene. In the context of human genetics, SNPs are the most common type of genetic variation, representing a difference in a single DNA building block. This specific variant has gained attention in neurogenetics research due to its identification as a lead locus in genome-wide association studies (GWAS) focused on Alzheimer's disease and related dementias (ADRD). The variant is situated in a region that has been linked to structural brain measurements, specifically the volume of the hippocampus. The hippocampus is a critical brain structure involved in memory and learning, and its atrophy is a well-known hallmark of neurodegenerative conditions. By studying this variant, researchers aim to better understand the genetic architecture that contributes to the structural changes observed in the brains of individuals with dementia.
The Role of the IGIP Gene
The IGIP gene, where rs156092 is located, has been previously implicated in Alzheimer's disease risk. While the exact functional consequences of the rs156092 variant are still being explored, its association with hippocampal volume suggests it may play a role in the biological pathways that maintain brain structure. Current research utilizes frameworks like the conjunctional false discovery rate (conjFDR) to identify shared genetic risk loci across different but related traits, such as ADRD and hippocampal volume. The identification of rs156092 as a lead locus in these analyses highlights its potential importance in the complex, polygenic nature of neurodegenerative disorders. It is important to emphasize that while this gene is a subject of active research, the field is still working to determine the precise molecular mechanisms by which this variant influences brain health and disease susceptibility.
Interpreting Research and Health Information
Information regarding the rs156092 variant is derived from ongoing scientific research and should be viewed as an evolving area of study. It is not a diagnostic tool, and the presence of this variant does not indicate that an individual will develop Alzheimer's disease or experience hippocampal volume loss. Alzheimer's is a multifactorial condition influenced by a combination of genetics, lifestyle, and environmental factors. If you have concerns about memory loss, cognitive decline, or family history of dementia, it is vital to consult with a neurologist or a primary care physician. They can provide appropriate clinical assessments, such as cognitive testing or neuroimaging, which are the standard for evaluating brain health. Genetic research provides valuable insights into the biological basis of disease, but it does not replace the need for professional medical evaluation and personalized care.
How common is this variant?
The rs156092 variant is noted as rare in the context of its specific association with ADRD and hippocampal volume phenotypes.
Frequently asked questions
What is the association between rs156092 and Alzheimer's?
rs156092 has been identified as a lead genetic locus associated with Alzheimer's disease and related dementias. Research suggests it is also linked to variations in hippocampal volume, a brain region affected by dementia.
Does rs156092 cause Alzheimer's disease?
No, this variant is a genetic marker associated with risk in a statistical sense. It is not a direct cause of the disease, and many factors contribute to the development of Alzheimer's.
Can I use this information to predict my risk?
No, individual genetic variants like rs156092 are not sufficient to predict personal risk for Alzheimer's disease. Risk assessment requires a comprehensive evaluation by a medical professional.
Where can I learn more about IGIP and brain health?
You can explore scientific databases like PubMed or the GWAS Catalog for peer-reviewed studies on IGIP and neurodegenerative research. Always prioritize information from reputable medical and scientific institutions.
