Genes affected

PCID2 (HGNC:25653): (PCI domain containing 2) This gene encodes a component of the TREX-2 complex (transcription and export complex 2), which regulates mRNA export from the nucleus. This protein regulates expression of Mad2 mitotic arrest deficient-like 1, a cell division checkpoint protein. This protein also interacts with and stabilizes Brca2 (breast cancer 2) protein. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

The c.725G>A (p.R242H) alteration is located in exon 10 (coding exon 10) of the PCID2 gene. This alteration results from a G to A substitution at nucleotide position 725, causing the arginine (R) at amino acid position 242 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
