The document describes LIPOchip, a DNA chip used to detect mutations related to Familial Hypercholesterolemia. It can detect over 240 mutations in the LDLR gene, 3 in the APOB gene, and 6 in the PCSK9 gene. It also detects copy number variations. The chip contains DNA fragments complementary to the target mutations. Samples are amplified, fragmented, labeled, and hybridized to the chip before being scanned and analyzed using specialized software.
