Genes affected

SGPL1 (HGNC:10817): (sphingosine-1-phosphate lyase 1) Enables sphinganine-1-phosphate aldolase activity. Involved in apoptotic signaling pathway; fatty acid metabolic process; and sphingolipid metabolic process. Located in endoplasmic reticulum. Implicated in nephrotic syndrome type 14.

This variant has not been reported in the literature in individuals affected with SGPL1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change creates a premature translational stop signal (p.Trp45*) in the SGPL1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SGPL1 are known to be pathogenic (PMID: 28165339, 28165343). For these reasons, this variant has been classified as Pathogenic. -
