Dr. Reardon is the Consulting Clinical Geneticist to the National Maternity Hospital and in this capacity sees many patients with genetic forms of infertility, patients during pregnancy where there is a potential fetal malformation or chromosomal problem, and also sees newborn infants with suspected genetic conditions. The genetic counselling of families thus identified is an essential part of his practice.
