Genes affected

OSBPL5 (HGNC:16392): (oxysterol binding protein like 5) This gene encodes a member of the oxysterol-binding protein (OSBP) family, a group of intracellular lipid receptors that play a key role in the maintenance of cholesterol balance in the body. Most members contain an N-terminal pleckstrin homology domain and a highly conserved C-terminal OSBP-like sterol-binding domain. This gene has been shown to be imprinted, with preferential expression from the maternal allele only in placenta. Transcript variants encoding different isoforms have been identified.

Ambry Genetics

Jan 10, 2023

The c.2420G>T (p.R807L) alteration is located in exon 21 (coding exon 20) of the OSBPL5 gene. This alteration results from a G to T substitution at nucleotide position 2420, causing the arginine (R) at amino acid position 807 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
