Genes affected

SCARF2 (HGNC:19869): (scavenger receptor class F member 2) The protein encoded by this gene is similar to SCARF1/SREC-I, a scavenger receptor protein that mediates the binding and degradation of acetylated low density lipoprotein (Ac-LDL). This protein has only little activity of internalizing modified low density lipoproteins (LDL), but it can interact with SCARF1 through its extracellular domain. The association of this protein with SCARF1 is suppressed by the presence of scavenger ligands. Alternatively spliced transcript variants encoding distinct isoforms have been reported.

The c.2588G>A (p.G863D) alteration is located in exon 11 (coding exon 11) of the SCARF2 gene. This alteration results from a G to A substitution at nucleotide position 2588, causing the glycine (G) at amino acid position 863 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
