Genes affected

OSBP2 (HGNC:8504): (oxysterol binding protein 2) The protein encoded by this gene contains a pleckstrin homology (PH) domain and an oxysterol-binding region. It binds oxysterols such as 7-ketocholesterol and may inhibit their cytotoxicity. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

The c.1012G>A (p.D338N) alteration is located in exon 3 (coding exon 3) of the OSBP2 gene. This alteration results from a G to A substitution at nucleotide position 1012, causing the aspartic acid (D) at amino acid position 338 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
