Genes affected

OSBPL7 (HGNC:16387): (oxysterol binding protein like 7) This gene encodes a member of the oxysterol-binding protein (OSBP) family, a group of intracellular lipid receptors. Like most members, the encoded protein contains an N-terminal pleckstrin homology domain and a highly conserved C-terminal OSBP-like sterol-binding domain. Two transcript variants encoding the same isoform have been identified. [provided by RefSeq, Jul 2008]

The c.2423G>A (p.R808Q) alteration is located in exon 23 (coding exon 22) of the OSBPL7 gene. This alteration results from a G to A substitution at nucleotide position 2423, causing the arginine (R) at amino acid position 808 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
