Genes affected
CENPN (HGNC:30873): (centromere protein N) The protein encoded by this gene forms part of the nucleosome-associated complex and is important for kinetochore assembly. It is bound to kinetochores during S phase and G2 and recruits other proteins to the centromere. Pseudogenes of this gene are located on chromosome 2. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Jul 2012]
CENPN-AS1 (HGNC:55106): (CENPN antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2021The c.656C>T (p.T219M) alteration is located in exon 8 (coding exon 7) of the CENPN gene. This alteration results from a C to T substitution at nucleotide position 656, causing the threonine (T) at amino acid position 219 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
