Genes affected

NR1H3 (HGNC:7966): (nuclear receptor subfamily 1 group H member 3) The protein encoded by this gene belongs to the NR1 subfamily of the nuclear receptor superfamily. The NR1 family members are key regulators of macrophage function, controlling transcriptional programs involved in lipid homeostasis and inflammation. This protein is highly expressed in visceral organs, including liver, kidney and intestine. It forms a heterodimer with retinoid X receptor (RXR), and regulates expression of target genes containing retinoid response elements. Studies in mice lacking this gene suggest that it may play an important role in the regulation of cholesterol homeostasis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

The c.866T>C (p.L289P) alteration is located in exon 6 (coding exon 5) of the NR1H3 gene. This alteration results from a T to C substitution at nucleotide position 866, causing the leucine (L) at amino acid position 289 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
