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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 30, 2023The c.1982C>T (p.P661L) alteration is located in exon 19 (coding exon 18) of the OSBPL8 gene. This alteration results from a C to T substitution at nucleotide position 1982, causing the proline (P) at amino acid position 661 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
