ENDOCRINE GENETICS LABORATORY: The laboratory seeks to elucidate the genetic determinants of insulin resistance and related conditions, using a population genetic approach. Particular areas of interest include insulin resistance and clearance and atherosclerosis in Hispanics and polycystic ovary syndrome. Technologies used include high-throughput genotyping of single nucleotide polymorphisms and other genetic markers. These markers are then analyzed for association with traits of interest. Positive results are followed by sequencing in critical gene regions to identify mutations that may be responsible for disease. Another research effort is the phenotyping of insulin resistance by physiologic infusion studies.
Discovery of genes involved in insulin resistance, metabolic syndrome, subclinical atherosclerosis, and polycystic ovary syndrome. Reported that processes whereby insulin is removed from the circulation are highly determined by genetic factors.
Current investigations include:
Ongoing investigation of genetic factors in polycystic ovary syndrome, particularly genes involved in adrenal androgen excess and response to metformin therapy. Investigating role of energy-related genes in insulin clearance. Search for genetic factors affecting the insulin system and subclinical atherosclerosis in Hispanic and other populations.
