Serine palmitoyltransferase, long chain base subunit 2, also known as SPTLC2, is a protein which in humans is encoded by the SPTLC2 gene.[1][2][3]

This gene encodes a long chain base subunit of serine palmitoyltransferase. Serine palmitoyltransferase, which consists of two different subunits, is the initial enzyme in sphingolipid biosynthesis. It catalyzes the pyridoxal 5'-phosphate dependent condensation of L-serine and palmitoyl CoA to 3-oxosphinganine. Mutations in this gene were identified in patients with hereditary sensory neuropathy type I. Alternatively spliced variants encoding different isoforms have been identified.[1]
