Genes affected

OSBPL10 (HGNC:16395): (oxysterol binding protein like 10) 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. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2010]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.1756G>A (p.E586K) alteration is located in exon 9 (coding exon 9) of the OSBPL10 gene. This alteration results from a G to A substitution at nucleotide position 1756, causing the glutamic acid (E) at amino acid position 586 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
