There's a newer better Microarray test that shows the bands of genes on a chromosome up to 2,000,000. It's called the SNP (pronounced snip) Microarray. The last test Sadie had a year and a half ago was the CGH Microarray, which showed up to 1,000 bands.
This is so important because genes control more than just hair and eye color, they also control, block, and communicate (epigenetics) with tumor receptors, cancer, other medical issues that might come up. Knowing which genes are missing, in Sadie's case, will help us keep a close eye on any potential medical issues. We know that Sadie is missing the gene that suppresses bladder tumors. So we will monitor her bladder.
Etc etc etc....
