Just SNP it.

SNPs, or single nucleotide polymorphisms, are those little variants in our DNA that companies like 23andMe use to tell us if our pee smells like asparagus for only $199. A lesser known feature is the ability to research your raw SNP data. Just enter the SNP and explore. Hence this study showing that an IL4 (rs2243250) variant is associated with the risk of severe radiation pneumonitis. Patients with CT or TT genotype are at a standard risk per dosimetric factors like V20 and mean lung dose (MLD). On the other hand, patients with the CC genotype were at a significantly increased risk of pneumonitis independent of V20 or MLD. | Tang, Radiother Oncol 2019
