EastEnders' icon Sharon Watts, played by Letitia Dean, very rarely gets a chance to catch her breath between the various twists and turns of her extraordinarily dramatic life, and the past few weeks have been no exception. After her son Albie's kidnap, doctors discovered he has Alpha-1 antitrypsin deficiency (AAT), a genetic condition that could lead to liver and lung disease later in life. Sharon was told that both she and Albie's dad Keanu Taylor (Danny Walters) would need to carry the gene for Albie to have it.
