Genes affected

CENPT (HGNC:25787): (centromere protein T) The centromere is a specialized chromatin domain, present throughout the cell cycle, that acts as a platform on which the transient assembly of the kinetochore occurs during mitosis. All active centromeres are characterized by the presence of long arrays of nucleosomes in which CENPA (MIM 117139) replaces histone H3 (see MIM 601128). CENPT is an additional factor required for centromere assembly (Foltz et al., 2006 [PubMed 16622419]).[supplied by OMIM, Mar 2008]

The c.1631G>A (p.R544Q) alteration is located in exon 16 (coding exon 13) of the CENPT gene. This alteration results from a G to A substitution at nucleotide position 1631, causing the arginine (R) at amino acid position 544 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
