Genomics for Precision Medicine in Arab and Middle Eastern Populations



Precision Medicine
is a new concept and an emerging model of healthcare where the genetic makeup and its interaction with the environment in incorporated towards enabling prevention, precise diagnosis and prognostication as well as precise treatment and management of a disease or condition.

A number of diseases are quite prevalent in the Arab world. A large part of this is attributed to the widespread practice and norm of consanguinity in the region. Understanding the genetic characteristics of many such diseases would provide the much necessary knowledge to build an effective healthcare system where early screening, early diagnosis and effective management cans significantly reduce the morbidity and mortality due to such diseases.

Landscape of Pharmacogenetic variants - Towards Precision Medicine in Qatar

Pharmacogenetic landscapes of commonly used anti-platelet drugs, warfarin and clopidogrel has been studied in-depth in many countries. However, there is a paucity of data to understand their patterns in the Arab populations. We characterized the allelic distribution of variants routinely tested for warfarin and clopidogrel in the publicly available whole exome sequencing datasets of 100 Qatar individuals . Our analysis points to ethnic differences in the frequencies of pharmacogenetics variants even for the small population studied. To the best of our knowledge, this is one of the first and most comprehensive pharmacogenetic maps of variants associated with warfarin and clopidogrel for an Arab population, which can help tailor the drug dosage to the population.
