Genes affected

CENPP (HGNC:32933): (centromere protein P) CENPP is a subunit of a CENPH (MIM 605607)-CENPI (MIM 300065)-associated centromeric complex that targets CENPA (MIM 117139) to centromeres and is required for proper kinetochore function and mitotic progression (Okada et al., 2006 [PubMed 16622420]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Oct 03, 2022

The c.162A>T (p.K54N) alteration is located in exon 2 (coding exon 2) of the CENPP gene. This alteration results from a A to T substitution at nucleotide position 162, causing the lysine (K) at amino acid position 54 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
