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.

The c.2246G>A (p.G749E) alteration is located in exon 19 (coding exon 18) of the OSBPL5 gene. This alteration results from a G to A substitution at nucleotide position 2246, causing the glycine (G) at amino acid position 749 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
