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]
PTOV1-AS1 (HGNC:44174): (PTOV1 antisense RNA 1)

The c.116C>T (p.A39V) alteration is located in exon 1 (coding exon 1) of the PTOV1 gene. This alteration results from a C to T substitution at nucleotide position 116, causing the alanine (A) at amino acid position 39 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
