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 links:

PNKP (HGNC:9154): (polynucleotide kinase 3'-phosphatase) This locus represents a gene involved in DNA repair. In response to ionizing radiation or oxidative damage, the protein encoded by this locus catalyzes 5' phosphorylation and 3' dephosphorylation of nucleic acids. Mutations at this locus have been associated with microcephaly, seizures, and developmental delay.[provided by RefSeq, Sep 2010]

Mar 23, 2022

The c.1171C>T (p.R391W) alteration is located in exon 11 (coding exon 11) of the PTOV1 gene. This alteration results from a C to T substitution at nucleotide position 1171, causing the arginine (R) at amino acid position 391 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
