Genes affected

CENPH (HGNC:17268): (centromere protein H) Centromere and kinetochore proteins play a critical role in centromere structure, kinetochore formation, and sister chromatid separation. The protein encoded by this gene colocalizes with inner kinetochore plate proteins CENP-A and CENP-C in both interphase and metaphase. It localizes outside of centromeric heterochromatin, where CENP-B is localized, and inside the kinetochore corona, where CENP-E is localized during prometaphase. It is thought that this protein can bind to itself, as well as to CENP-A, CENP-B or CENP-C. Multimers of the protein localize constitutively to the inner kinetochore plate and play an important role in the organization and function of the active centromere-kinetochore complex.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.98C>T (p.A33V) alteration is located in exon 1 (coding exon 1) of the CENPH gene. This alteration results from a C to T substitution at nucleotide position 98, causing the alanine (A) at amino acid position 33 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
