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-AS2 (HGNC:51284): (PTOV1 antisense RNA 2)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.765C>G (p.N255K) alteration is located in exon 7 (coding exon 7) of the PTOV1 gene. This alteration results from a C to G substitution at nucleotide position 765, causing the asparagine (N) at amino acid position 255 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
