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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.2119G>C (p.E707Q) alteration is located in exon 20 (coding exon 19) of the OSBPL7 gene. This alteration results from a G to C substitution at nucleotide position 2119, causing the glutamic acid (E) at amino acid position 707 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
