Genes affected

SLC27A1 (HGNC:10995): (solute carrier family 27 member 1) Enables biotin transmembrane transporter activity; efflux transmembrane transporter activity; and long-chain fatty acid transporter activity. Involved in several processes, including carboxylic acid transmembrane transport; glycerophospholipid biosynthetic process; and lipid transport across blood-brain barrier. Located in membrane. Part of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

PGLS-DT (HGNC:55274): (PGLS divergent transcript)
