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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.199C>T (p.L67F) alteration is located in exon 4 (coding exon 2) of the CENPL gene. This alteration results from a C to T substitution at nucleotide position 199, causing the leucine (L) at amino acid position 67 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
