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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 13, 2024The c.1127G>A (p.R376H) alteration is located in exon 6 (coding exon 6) of the OSBP gene. This alteration results from a G to A substitution at nucleotide position 1127, causing the arginine (R) at amino acid position 376 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
