Genome Variations
Dilemma in genotype to phenotype prediction : Sickle cell mutation
Sickle cell mutation Normal RBC mutant Disease modifying genes
Environment Primary mutation Intermediate patho-phenotype
Patho-phenotypes Current challenge: Identifying patterns from possibilities Predictive, Preventive, Personalised & Participatory (P4) medicine
• Prevalence of common and complex disorder & also combined monogenic disorders is 1-5% in all populations • Life time prevalence, Increased life expectancy , long term medications, side effects of therapeutic intervention further add to the global health burden • Major aim is to prevent disease or maintain quality of life
GIS of a human P4 medicine vis-à-vis Ayurveda
Aim: Maintenance of health in healthy & alleviation of disorders in diseased
TRISUTRA (subject matter)
Hetu/Causes • Each axis- as Independent science EEF & IEF • Interconnections – subject matter for Healthy Translational Medicine & Diseased • Stratified Approach – important for Predictive & Personalized medicine Linga/laksanas Aushadha/ Features Therapeutics

C.Su.1/24 Tridoshas: common organizing principle
The proportion of Vata, Pitta & Kapha invariant in an individual
Doshas are restrained within normal limits in health
Perturbation in doshic proportions beyond threshold leads to disease
Goal of treatment is restoration of basal levels
Three most contrasting types are the most vulnerable
