44% reduction of SPT activity in patiens with hereditary sensory neuropathy type I with mutation T399G in the SPTLC1 gene. However the decrease in SPT activity has no effect on de novo sphingolipid biosynthesis, cellular sphingolipid content, cell proliferation and death. Despite the inhibition of mutant allele, the activity of nonmutant allele of SPT may be sufficient for adequate sphingolipid biosynthesis and cell viability. The neurodegeneration in HSN1 is likely to be caused by subtler and rather long-term effects of these mutations such as loss of a cell-type selective facet of sphingolipid metabolism and/or function, or perhaps accumulation of toxic species, including abnormal proteins

1-deoxysphingolipids are atypical sphingolipids that are formed by the enzyme serine palmitoyltransferase due to a promiscuous use of L-alanine over its canonical substrate L-serine. Wild-type SPT forms 1-deoxysphingolipids under certain conditions, and elevated levels are found in individuals with the metabolic syndrome and diabetes
