Genes affected

PCM1 (HGNC:8727): (pericentriolar material 1) The protein encoded by this gene is a component of centriolar satellites, which are electron dense granules scattered around centrosomes. Inhibition studies show that this protein is essential for the correct localization of several centrosomal proteins, and for anchoring microtubules to the centrosome. Chromosomal aberrations involving this gene are associated with papillary thyroid carcinomas and a variety of hematological malignancies, including atypical chronic myeloid leukemia and T-cell lymphoma. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2015]

The c.313C>G (p.Q105E) alteration is located in exon 4 (coding exon 2) of the PCM1 gene. This alteration results from a C to G substitution at nucleotide position 313, causing the glutamine (Q) at amino acid position 105 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
