One-Stop Genetic Test For Embryos Unveiled

06 July 2009 - by Dr Will Fletcher

A one-step gene mapping test for identifying genetic and chromosomal abnormalities in embryos may be available in the UK within a year. The technique, known as karyomapping, can screen for almost any inherited disease and is much faster than those currently available as it does not need prior knowledge of the specific gene mutation involved. The method was unveiled last week at the annual conference of the European Society for Human Reproduction and Embryology (ESHRE), in Amsterdam, after res... [Read More]

Genetic variations linked to schizophrenia
