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 GeneticsApr 22, 2022The c.998T>C (p.L333P) alteration is located in exon 10 (coding exon 10) of the PTOV1 gene. This alteration results from a T to C substitution at nucleotide position 998, causing the leucine (L) at amino acid position 333 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
