Genes affected

OIP5 (HGNC:20300): (Opa interacting protein 5) The protein encoded by this gene localizes to centromeres, where it is essential for recruitment of CENP-A through the mediator Holliday junction recognition protein. Expression of this gene is upregulated in several cancers, making it a putative therapeutic target. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2015]

OIP5 links:

OIP5-AS1 (HGNC:43563): (OIP5 antisense RNA 1) This is a conserved gene that produces a long non-coding RNA that maintains cell proliferation in embryonic stem cells. This RNA can bind to and negatively regulate the activity of multiple cellular RNAs and microRNAs, including cyclin G associated kinase and ELAV like RNA binding protein 1.

Ambry Genetics

Apr 26, 2023

The c.596T>C (p.L199P) alteration is located in exon 5 (coding exon 5) of the OIP5 gene. This alteration results from a T to C substitution at nucleotide position 596, causing the leucine (L) at amino acid position 199 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
