The MMGL Molecular Genetics Laboratory functions under the direction of Dr. Chen Yang and emphasizes testing for diseases that are predominantly caused by inherited changes in one or more genes. A particular focus is the development and implementation of testing for rare conditions using DNA sequencing, methylation analysis, array-based gene dosage analysis, quantitative PCR and selected SNP testing. A Research and Development component promotes research to expand testing capabilities for new conditions and the use of genetic tools in decisions affecting care.
