Inactivating mutations in MFSD2A , required for omega-3 fatty acid transport in brain, cause a lethal microcephaly syndrome

Joseph Gleeson, David Silver and colleagues show that inactivating mutations in MFSD2A , which encodes an essential transporter of long-chain fatty acids in brain, cause a lethal microcephaly syndrome. These results establish a link between the activity of this transporter and human brain growth.
