Fifteen-year hunt uncovers gene behind 'pseudothalidomide' syndrome
... a gene called ESCO2 that was identical in all the animals
contained changes that disrupted the gene's protein-making instructions in people with the syndrome. Knocking out the equivalent gene in yeast and fruit flies led to the same chromosome problems, says Gordillo. "Comparative genomics didn't really ex...
