Genes affected

OSBPL1A (HGNC:16398): (oxysterol binding protein like 1A) 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. Transcript variants derived from alternative promoter usage and/or alternative splicing exist; they encode different isoforms. [provided by RefSeq, Jul 2008]

The c.2369A>G (p.Y790C) alteration is located in exon 24 (coding exon 23) of the OSBPL1A gene. This alteration results from a A to G substitution at nucleotide position 2369, causing the tyrosine (Y) at amino acid position 790 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
