Genes affected

APOL2 (HGNC:619): (apolipoprotein L2) This gene is a member of the apolipoprotein L gene family. The encoded protein is found in the cytoplasm, where it may affect the movement of lipids or allow the binding of lipids to organelles. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

The c.805A>G (p.S269G) alteration is located in exon 6 (coding exon 3) of the APOL2 gene. This alteration results from a A to G substitution at nucleotide position 805, causing the serine (S) at amino acid position 269 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
