Genes affected

CENPL (HGNC:17879): (centromere protein L) CENPL 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]

Collection Method:clinical testing

The c.295A>G (p.I99V) alteration is located in exon 4 (coding exon 2) of the CENPL gene. This alteration results from a A to G substitution at nucleotide position 295, causing the isoleucine (I) at amino acid position 99 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
