Genes affected

PSRC1 (HGNC:24472): (proline and serine rich coiled-coil 1) This gene encodes a proline-rich protein that is a target for regulation by the tumor suppressor protein p53. The encoded protein plays an important role in mitosis by recruiting and regulating microtubule depolymerases that destabalize microtubules. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Apr 2014]

The c.989G>A (p.G330E) alteration is located in exon 7 (coding exon 6) of the PSRC1 gene. This alteration results from a G to A substitution at nucleotide position 989, causing the glycine (G) at amino acid position 330 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
