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.436A>C (p.K146Q) alteration is located in exon 7 (coding exon 5) of the OSBPL6 gene. This alteration results from a A to C substitution at nucleotide position 436, causing the lysine (K) at amino acid position 146 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
