CRC Number: 99-17 Genotype and Phenotype Relationships of Two MTHFR Alleles in a Multi-Ethnic Population Principal Investigator: Steven E. Seifried, PhD Co-Principal Investigator: Andrew Grandinetti, PhD Co-Principal Investigator: Healani Chang, PhD Abstract Four prevalent ethnic populations in the State of Hawaii will be characterized in respect to the incidence and distribution of two mutations in the methylenetetrahydrofolate reductase (MTHFR) gene, thought to contribute to cardiovascular disease risk. The relationships between plasma homocysteine levels (tHcy), cardiovascular health status and these alleles will be examined in a merge of clinical sciences with the basic science tools of genetics to increase our understanding of the molecular medicine and epidemiology of cardiovascular disease. Four different ethnicities within the Native Hawaiian Health Project’s North Kohala Multi-Ethnic Cohort will be examined with identical behavioral, phenotypic, and genotypic analytical tools, thereby allowing effective comparisons. The central hypothesis to be tested is whether a newly described second variant allele exerts phenotypic expression in the same fashion for plasma homocysteine levels as it does for neural tube defect risk. We will also examine the distribution of the two common variant alleles with the four ethnic groups. We will identify individuals whose tHcy levels do not correlate with determined genotype, and look for epigenetic or additional genetic factors leading to unexpected homocysteine levels. Results may lead to early identification of high risk individuals or to new approaches to modulate tHcy levels. This is especially relevant to the Native Hawaiian population, who has CVD and diabetic risks several fold higher than the general population of the United States.

84. GUESS Study: Inconsistencies By Experts In Interpreting Resistance Test Results phenotypic resistance from genotype resistance test results; (2) there was variableagreement among experts in translating genotype to phenotype or drug http://www.natap.org/2002/barcelona/day13.htm

Conference Reports for NATAP AIDS 2002 Barcelona Barcelona, Spain July 7-12 2002 Back GUESS Study: inconsistencies by experts in interpreting resistance test results Reported by Jules Levin This report contains results from 2 studies reflecting the difficulties in using resistance testing. Also in this report is a commentary by me on using resistance testing. I think resistance testing can be helpful in making treatment decisions in the hands of the right person but I also think test results in the wrong hands can be harmful. Education about resistance testing is crucial. Refining The Use of Resistance Testing (Commentary) Some researchers believe the genotype test is more reliable while others believe the phenotype is more reliable. If you have the resources it might be better to do both tests but make sure your treatment history is adequately considered, and that whoever is making a treatment recommendation to you knows what they are doing. Bear in mind, improper interpretation of a test result or printout from the lab conducting the test can result in a bad treatment decision. Also bear in mind that reliance on the lab test recommendation can be a mistake, as their interpretation can be wrong. If you get a genotypic mutation or several reported on a test result this can rule out the usefulness of certain drugs. But the absence of detectable resistance does not mean that you don't have resistance; it may just not be detectable. See how complicated resistance testing can be. Some lab test results, for example a Quest lab test result, may say you are sensitive to AZT but you may have very little sensitivity to AZT. Does your doctor understand all these subtle complications? Or does he/she just read the sometimes faulty recommendations on the printed lab test result the doctor receives?
