Genes affected

OSBPL9 (HGNC:16386): (oxysterol binding protein like 9) 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, although some members contain only the sterol-binding domain. This family member functions as a cholesterol transfer protein that regulates Golgi structure and function. Multiple transcript variants, most of which encode distinct isoforms, have been identified. Related pseudogenes have been identified on chromosomes 3, 11 and 12. [provided by RefSeq, Jul 2010]

Ambry Genetics

Oct 28, 2023

The c.4G>A (p.A2T) alteration is located in exon 1 (coding exon 1) of the OSBPL9 gene. This alteration results from a G to A substitution at nucleotide position 4, causing the alanine (A) at amino acid position 2 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
