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]

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Nov 06, 2023	This sequence change creates a premature translational stop signal (p.Ser1081Argfs*8) in the CENPJ gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CENPJ are known to be pathogenic (PMID: 15793586, 16900296, 20522431). This variant is present in population databases (rs199422203, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with CENPJ-related conditions (PMID: 34958143, 35229910). ClinVar contains an entry for this variant (Variation ID: 1819). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. For these reasons, this variant has been classified as Pathogenic. -
