rs4673, also known as C242T or H72Y, is a SNP in the NAD(P)H oxidase p22(phox) subunit CYBA gene on chromosome 16.
The rs4673(T) allele, and specifically (T;T) genotype, has been reported in several studies to be associated with reduced risk for cardiovascular disease risk, such as hypertension, atherosclerosis, and myocardial infarction, and to reduce oxidative burst in neutrophils.[PMID 18184111],[PMID 15860042],[1],[PMID 15078863]
However, other studies have found no support for this, or even found the opposite. For example, a study of German patients with ischemic stroke or transient ischemic attack under the age of 50 (n = 161) concluded that rs4673(T;T) individuals were almost 4 times more likely to experience cerebral ischemia (odds ratio 3.85, CI: 1.39-10.64) compared to rs4673(C;T) or (C;C) individuals after adjusting for classical risk factors.[PMID 18799874]
Whether the variant reduces or increases risk may even depend on the ethnic group in question. [PMID 20100625] A meta-analysis concluded that the T allele effect may vary between ethnicities in both direction of effect and significance; Asian populations may have reduced coronary artery disease risk associated with the T allele.
