Genes affected

OSBPL8 (HGNC:16396): (oxysterol binding protein like 8) This gene encodes a member of a family of proteins containing an N-terminal pleckstrin homology domain and a highly conserved C-terminal oxysterol-binding protein-like sterol-binding domain. It binds mutliple lipid-containing molecules, including phosphatidylserine, phosphatidylinositol 4-phosphate (PI4P) and oxysterol, and promotes their exchange between the endoplasmic reticulum and the plasma membrane. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

The c.1385T>C (p.L462S) alteration is located in exon 13 (coding exon 12) of the OSBPL8 gene. This alteration results from a T to C substitution at nucleotide position 1385, causing the leucine (L) at amino acid position 462 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
