Genes affected
MFSD2A (HGNC:25897): (MFSD2 lysolipid transporter A, lysophospholipid) The protein encoded by this gene is a transmembrane protein and sodium-dependent lysophosphatidylcholine transporter. The encoded protein is involved in the establishment of the blood-brain barrier and is required for brain growth and function. Defects in this gene are a cause of a progressive microcephaly syndrome.
