Risk of Developing Periodontitis Based on:
  • CPMC Periodontitis Variant 1 (rs1143634)
  • Smoking


The CPMC is a research study investigating the utility of personalized genomic information on health and health behavior. At this time, the CPMC is reporting one genetic variant per health condition. Since most common health conditions are caused by an interaction between more than one genetic factor and non-genetic factors such as lifestyle, the genetic variant risk in this report does not represent your complete genetic risk for periodontitis. These results were generated as part of this research study in a CLIA-approved laboratory.

More information about the study, how to interpret CPMC results, and how we calculate risk is available on our website http://cpmc.coriell.org or by contacting our genetic counselors. Participants may schedule an appointment with one of our board-certified genetic counselors through the web portal by clicking on “request an appointment”. Our genetic counselors also can be reached by email at cpmcgc@coriell.org or by phone at 888-580-8028.

This research report includes all data included in the clinical report as well as supplemental interpretations and educational material. Please see the report that follows for the official clinical report.
 
Periodontitis
Risk factors may be related to each other and risk estimates cannot be combined.
This graph provides a summary of the relative risks for the genetic variant and smoking.
You reported you are between 20 and 34 years old; 4 in 100 people in your age group have periodontitis.
Chart Color Relative Risk Due To: Your Risk Minimum Risk Maximum Risk Interpretation
   Genetic Variant 1.00 1.00 1.50 You have 2 copies of the non-risk variant. Based this result, you are at lower risk to develop periodontitis compared to someone with one or two copies of this variant.
   Smoking Status 1.00 1.00 3.20 Because you are not a smoker, you are at a lower risk to develop periodontitis compared to current and former smokers.
 
Periodontitis
Risk Due To Genetic Variant #1 (rs1143634)
Your Result: 2 copies of the non-risk variant were detected (GG)
Non-Risk Variant = G      Risk Variant = A
Chart Color Your Risk Minimum Risk Maximum Risk Interpretation
   1.00 1.00 1.50 You have 2 copies of the non-risk variant. Based this result, you are at lower risk to develop periodontitis compared to someone with one or two copies of this variant.
Genetic variant risk is based on the number of copies of this genetic risk variant.

People with one or two copies of the risk variant are compared to people with no copies of the risk variant to determine relative risk.

A relative risk greater than 1.0 indicates an increased risk.
These risk estimates are based on studies in Caucasian populations.
 
Periodontitis
Risk Due To Smoking Status
You reported that you do not smoke.
Chart Color Your Risk Minimum Risk Maximum Risk Interpretation
   1.00 1.00 3.20 Because you are not a smoker, you are at a lower risk to develop periodontitis compared to current and former smokers.
Risk is compared based on smoking habits.

People who are current smokers or former smokers are compared to people who have never smoked to determine relative risk.

A relative risk of greater than 1.0 indicates an increased risk.
These results are based on a study conducted in multiple populations of different racial and ethnic backgrounds.
 
Periodontitis - Variant #1 (rs1143634)
We all have 2 copies of every gene, one from each of our parents.
Each copy may have small changes called genetic variants.
Some genetic variants are associated with an increased risk of disease.
Some genetic variants are associated with a decreased risk of disease.

Having one or two copies of this variant increases the risk for periodontitis.
How Common Is This Variant?
Non-Risk Variant = G      Risk Variant = A
GG - 80 in 100 people have 2 copies of the non-risk variant
GA - 20 in 100 people have 1 copy of the non-risk variant and 1 copy of the risk variant
AA - 0 in 100 people have 2 copies of the risk variant
This data is based on studies in African American populations.










Gene: IL1B Chromosome: 2q13
 
Genetic vs. Non-Genetic Risk Factors
Periodontitis can be caused by both genetic factors and non-genetic (or environmental) risk factors.

It is estimated that non-genetic factors (like smoking) account for about 58% of the risk of periodontitis.

It is estimated that 42% of the risk for periodontitis is based on genetic risk factors. This estimate accounts for both known and unknown gene variants.

There are many different genetic and non-genetic risk factors that contribute to the risk of periodontitis. We are only able to tell you about 1 genetic and 1 non-genetic risk factor at this time.
 
Periodontitis is more common among cigarette smokers.

You reported you are between 20 and 34 years old; 4 in 100 people in your age group have periodontitis.
 
Periodontitis
  • This result alone does NOT diagnose periodontitis. Periodontitis must be diagnosed by your health care provider.
  • This result does NOT mean that you have or will absolutely develop periodontitis. This result does NOT mean that you will not develop periodontitis in the future.
  • This result ONLY assesses your risk for developing periodontitis due to the factors presented in this report and does not mean that other genetic variants or risk factors for periodontitis are present or absent.
  • Personal risk factors, such as age, family history or lifestyle, may have a greater impact on your risk to develop periodontitis than any individual genetic variant.
  • Risk estimates are based on current available literature.
  • Although rare, it is possible that you may receive an incorrect result; 100% accuracy of reported results cannot be guaranteed.
  • Occasionally there may be a specific variant on a gene chip that is not able to be read or interpreted. In this case you will not receive a result for that variant. It is expected that you will receive results for about 95% of variants approved by the ICOB.
  • Relative risks used to estimate risk of disease for CPMC participants are based on groups of people with the same risk or protective factor as the individual CPMC participant. In some cases, the relative risk is estimated based upon an odds ratio and known or assumed disease prevalence.
  • Separate risk estimates for each risk or protective factor have been given. Risk or protective factors may be related to each other and risk estimates cannot be combined.
  • Risk information for non-genetic factors is based on information you provided in your medical, family, lifestyle questionnaire. If you did not provide answers or if you answered “do not know”, risk estimates for some factors may not be available.
  • Risk information for non-genetic factors is based on information you provided in your medical, family, lifestyle questionnaire and may not be reflective of your current risk if any of these factors have changed. You will be given the opportunity to update your medical, family and lifestyle questionnaire responses periodically.
  • Every effort will be made to provide you with risk information based on your reported race/ethnicity. However, data may not be available for all races/ethnicities for all risk factors. Please see your individual results to determine which race/ethnicity the data given is based on.
  • For some risk factors data may be provided by gender. Every effort will be made to provide you with risk information based on your reported gender. However, when risk data is not available for both genders, risk results for the available gender will be provided.

Periodontitis
This condition and genetic variant(s) were approved by the Informed Cohort Oversight Board (ICOB)
Test Methodology
Saliva samples were collected using Oragene DNA Collection Kits (DNA Genotek) and DNA was extracted manually according to the manufacturer’s instructions. Purified DNA was quantified using UV absorbance at 260 nm. Five hundred nanograms of the resulting DNA from each sample were used as template in the Affymetrix Genome-Wide Human SNP Nsp/Sty 6.0 GeneChip assay. Data analysis was performed using Affymetrix Genotyping Console software.

Risk interpretation based on Coriell's Periodontitis Risk Algorithm Version 1 (June 11, 2013)
Test Limitations
DNA-based testing is highly accurate, however there are many sources of potential error including: mis-identification of samples, rare technical errors, trace contamination of PCR reactions, and rare genetic variants that interfere with analysis. There may be other variants, not included in this test, that influence the risk to develop periodontitis. This test is not diagnostic for periodontitis and cannot rule out the risk of developing periodontitis in the future. Risk estimates are based on current available literature (see reference). This test or one or more of its components was developed and its performance characteristics determined by the Coriell Institute for Medical Research. It has not been approved by the Food and Drug Administration (FDA). The FDA has determined that such approval is not necessary. The Coriell Institute is regulated under the Clinical Laboratory Improvement Amendments (CLIA) of 1988 as qualified to perform high-complexity testing.
Test Methodology
Saliva samples were collected using Oragene DNA Collection Kits (DNA Genotek) and DNA was extracted manually according to the manufacturer’s instructions or automatically using a DNAdvance Kit (Agencourt). Purified DNA was quantified using UV absorbance at 260 nm. Five hundred nanograms of the resulting DNA from each sample were used as template in the Affymetrix Genome-Wide Human SNP Nsp/Sty 6.0 GeneChip assay. Data analysis was performed using Affymetrix Genotyping Console software.
