Genes affected

OSBPL6 (HGNC:16388): (oxysterol binding protein like 6) This gene encodes a member of the oxysterol-binding protein (OSBP) family, a group of intracellular lipid receptors. Most members contain an N-terminal pleckstrin homology domain and a highly conserved C-terminal OSBP-like sterol-binding domain. Transcript variants encoding different isoforms have been identified.

The c.707G>A (p.S236N) alteration is located in exon 9 (coding exon 7) of the OSBPL6 gene. This alteration results from a G to A substitution at nucleotide position 707, causing the serine (S) at amino acid position 236 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
