Genes affected

PTOV1 (HGNC:9632): (PTOV1 extended AT-hook containing adaptor protein) This gene encodes a protein that was found to be overexpressed in prostate adenocarcinomas. The encoded protein was found to interact with the lipid raft protein flotillin-1 and shuttle it from the cytoplasm to the nucleus in a cell cycle dependent manner. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Feb 2015]

The c.128G>A (p.G43D) alteration is located in exon 1 (coding exon 1) of the PTOV1 gene. This alteration results from a G to A substitution at nucleotide position 128, causing the glycine (G) at amino acid position 43 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
