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.
