Prenatal diagnosis of Chediak-Higashi syndrome.

abstract：:Non-invasive prenatal testing has been in clinical use for a decade; however, there is evidence that this technology will be more widely applied within the next few years. Guidance is therefore required to ensure that the procedure is offered in a way that is evidence based and ethically and clinically acceptable. We ...
