Genes affected

CENPO (HGNC:28152): (centromere protein O) This gene encodes a component of the interphase centromere complex. The encoded protein is localized to the centromere throughout the cell cycle and is required for bipolar spindle assembly, chromosome segregation and checkpoint signaling during mitosis. Alternatively spliced transcript variants encoding multiple protein isoforms have been observed for this gene. [provided by RefSeq, Dec 2010]

The c.442C>T (p.L148F) alteration is located in exon 5 (coding exon 4) of the CENPO gene. This alteration results from a C to T substitution at nucleotide position 442, causing the leucine (L) at amino acid position 148 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
