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 GeneticsMar 11, 2022The c.2159G>A (p.R720Q) alteration is located in exon 20 (coding exon 19) of the OSBPL8 gene. This alteration results from a G to A substitution at nucleotide position 2159, causing the arginine (R) at amino acid position 720 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
