Garry R. Cutting, M.D.

Medical Laboratory Director, Professor of Genetic Medicine

Dr. Cutting earned his B.S. in Biology from the University of Connecticut and his M.D. from the University of Connecticut Medical School. 他在约翰霍普金斯大学医学院完成了儿科遗传学的研究. 他的研究重点是囊性纤维化(CF)疾病变异的遗传和非遗传原因，他的研究实验室有三个主要的活跃项目:CF双胞胎和兄弟姐妹研究, Genetic Heterogeneity in CF, CFTR2 Project.

CF双胞胎和兄弟姐妹研究旨在确定导致CF表型变异的主要遗传和环境因素. 采用全基因组连锁和关联方法寻找修饰数量性状(肺功能)的位点和基因, BMI) and qualitative complications (diabetes and meconium ileus) of CF. 遗传异质性研究正在调查实验室招募的有2个或更多个体的家庭，这些家庭的连锁关系排除了CFTR的参与. 外显子组测序被用来发现产生cf样表型的新基因. CFTR2 is a worldwide project involving ~70,对CFTR基因的所有突变进行临床和功能上的注释.
