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 GeneticsJun 22, 2024The c.764T>C (p.I255T) alteration is located in exon 3 (coding exon 3) of the OSBP gene. This alteration results from a T to C substitution at nucleotide position 764, causing the isoleucine (I) at amino acid position 255 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
