The presence of an [[rs173686]](C) allele has been linked to increased risk of a certain type of stroke, [[Intracranial Aneurysm]], in a population of Dutch adults. {{PMID|16917090}}

A study of 240 Chinese Han nationality patients with at least one intracranial aneurysm and matched controls did not replicate this result.{{PMID|18484070}}

Note: the dbSNP sequence entry for this SNP represents the noncoding strand, and is thus the reverse complement compared to the SNP as referred to in {{PMID|16917090}}.
