Increased risk of intracranial (brain aneurysm) with certain SNPs. rs700651(G;G) associated with 1.56x risk of developing an intracranial aneurysm (IA). Heterozygote risk is 1.18x. Other SNPs associated with increased risk of developing IA include rs1333040 and rs10958409.
rs10958409 is located on chromosome 9; rs1333040 is located on chromosome 8; rs700651 is located on chromosome 2.
Unfortunately, the first sign of an intracranial aneurysm is rupture. Catastrophic bleeding and death may result. Specific knowledge of risk may influence screening decision. More information: Intracranial aneurysm screening: indications and advice for practice. [PMID 15664544]
