Genes affected

PRC1 (HGNC:9341): (protein regulator of cytokinesis 1) This gene encodes a protein that is involved in cytokinesis. The protein is present at high levels during the S and G2/M phases of mitosis but its levels drop dramatically when the cell exits mitosis and enters the G1 phase. It is located in the nucleus during interphase, becomes associated with mitotic spindles in a highly dynamic manner during mitosis, and localizes to the cell mid-body during cytokinesis. This protein has been shown to be a substrate of several cyclin-dependent kinases (CDKs). It is necessary for polarizing parallel microtubules and concentrating the factors responsible for contractile ring assembly. Alternative splicing results in multiple transcript variants.

Collection Method: clinical testing

The c.1672G>T (p.G558C) alteration is located in exon 13 (coding exon 13) of the PRC1 gene. This alteration results from a G to T substitution at nucleotide position 1672, causing the glycine (G) at amino acid position 558 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
