Medical Problem Solving, Case 2: What is the Cause of the Seizures?

Overview & Concepts

This activity is focused around a case study. Students use various data tools and data sets (including OMIM, pedigree analysis, 10K Microarray / SNP data and the Genome browser) to identify candidate genes.  After locating the gene, students use BLAST and BLAT to learn more about the type of mutation and normal function of the gene.

Grade Level: 

Concepts Covered: 

OMIM, BLAT, BLAST, microarrays, single nucleotide polymorphisms, 10 K microarragy, SNP
 

Prior Knowledge Required: 

DNA, genes, chromosomes, pedigree, PCR
