| To find a treatment, researchers first have to find a cause, a mutation or malfunction in one or more genes. The mutation they are looking for could literally be any one of 3.1 billion base pairs | |

| Using microarrays to genotype 10,000 or even 100,000 SNPs, researchers can pinpoint the gene, or group of genes, that’s contributing to disease. | |

| Diseases usually develop when a person is homozygous for a SNP genotype. | |
| | |
|
|
| | |
| When that happens, it means that you inherited the same faulty chunk of DNA from both your mom and your dad; hence the SNP genotypes are the same. | |
