The protein encoded by this gene catalyzes the reduction of 3-ketodihydrosphingosine to dihydrosphingosine. The putative active site residues of the encoded protein are found on the cytosolic side of the endoplasmic reticulum membrane. A chromosomal rearrangement involving this gene is a cause of follicular lymphoma, also known as type II chronic lymphatic leukemia. The mutation of a conserved residue in the bovine ortholog causes spinal muscular atrophy. [provided by RefSeq, Jul 2008] (from

FVT1 is significantly underexpressed by germinal center-type diffuse large B-cell lymphoma compared with non-germinal center-type DLBCL, follicular lymphoma, & normal tonsil control samples. Increased expression of FVT1 correlated with decreased survival.
