Genes affected

CENPJ (HGNC:17272): (centromere protein J) This gene encodes a protein that belongs to the centromere protein family. During cell division, this protein plays a structural role in the maintenance of centrosome integrity and normal spindle morphology, and it is involved in microtubule disassembly at the centrosome. This protein can function as a transcriptional coactivator in the Stat5 signaling pathway, and also as a coactivator of NF-kappaB-mediated transcription, likely via its interaction with the coactivator p300/CREB-binding protein. Mutations in this gene are associated with primary autosomal recessive microcephaly, a disorder characterized by severely reduced brain size and cognitive disability. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Apr 2012]

Likely pathogenic, criteria provided, single submitter	clinical testing	Molecular Genetics Department, Kulakov National Medical Research Center for Obstetrics, Gynecology and Perinatology	-	A previously undescribed nucleotide variant creates a premature translation stop signal p.Ser529Ter in the CENPJ gene. The variant was observed in presumably compound heterozygous state with another LoF variant (phase not tested) in an individual affected with microcephaly and micrognathia. Homozygous and compound heterozygous variants are reported in patients with Microcephaly 6, primary, autosomal recessive, 608393, and Seckel syndrome 4, 613676. The variant is present in gnomAD population database at low frequency (24/250986 chromosomes, no homozygotes). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as likely pathogenic. -
