Genes affected
OSBP (HGNC:8503): (oxysterol binding protein) Oxysterol binding protein is an intracellular protein that is believed to transport sterols from lysosomes to the nucleus where the sterol down-regulates the genes for the LDL receptor, HMG-CoA reductase, and HMG synthetase [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 27, 2024The c.1421G>C (p.C474S) alteration is located in exon 8 (coding exon 8) of the OSBP gene. This alteration results from a G to C substitution at nucleotide position 1421, causing the cysteine (C) at amino acid position 474 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
