ACE Inhibitor (ACE-I) induced cough

ACE-I induced cough is a common side effect of use of ACE inhibitors, one of the most common class of antihypertensives.  The frequency of ACEI-induced cough varies based on ancestry.  A GWAS of ACEI cough using this algorithm in the eMERGE Network identified KCNIP4 as associated with this phenotype, which was validated in two replication cohorts. 

Cases are those with ACEI cough.  Controls are those exposed to ACEI without adverse events noted and not switched to angiotensin receptor blockers (ARBs).  

Algorithm validated - December 12, 2012.

Appendicitis

Appendicitis is one of the most common acquired surgical conditions of childhood.  Diagnosis of appendicitis remains difficult.  Much work has been done on validation of clinical scores to reduce the number of unnecessary surgeries and radiographic tests while maintaining a high sensitivity for disease.  However, no score performs well enough in practice to reduce these risks (Kulik et al., 2013).  It is also known that appendicitis has a familial predominance, but little is known about the genetic factors that may increase a certain child's risk for the condition (Oldmeadow et al., 2009).

Body Mass Index (BMI)

eMERGE-IV BMI Algorithm adapted from Geisinger Extreme Obesity Algorithm (2013). BMI is being implemented as a quantitative trait. PheKB maintains a catalog of the Geisinger Extreme Obesity algorithm, on which this is based (Phenotpe 121). This algorithm is for analysis. Sites only contributing covariates can simply compile the designated data.

Breast Cancer

Breast cancer is the most common cancer and the second leading cause of cancer-related death among women in the U.S. Known breast cancer risk factors include age, race/ethnicity, reproductive factors, and benign breast disease. Family history of breast cancer and hereditary cancer syndromes, such as BRCA1/BRCA2 mutations, confer the strongest risk for this disease.

Breast Cancer: PRIMED General Harmonization

These are the PRIMED General Harmonization instructions for breast cancer (BC). We are using the breast cancer definition used by the eMERGE program, with some additional data types included. These instructions expand to include data structures from cohort, EHR, biobank, and OMOP structured data as these vary across studies and available data.

Please see Breast Cancer: PRIMED Legacy Harmonization for a more narrowed down definition for implementation.
