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]

The p.Glu300ThrfsX7 variant in CENPJ has been reported in one individual with Se ckel syndrome (ClinVar Variation ID #210670). It has been identified in 2/113580 of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). Although this variant has been seen in the general population, its frequency is low enoug h to be consistent with a recessive carrier frequency. This variant is predicted to cause a frameshift, which alters the protein?s amino acid sequence beginning at position 300 and leads to a premature termination codon 7 amino acids downst ream. This alteration is then predicted to lead to a truncated or absent protein . Biallelic loss of function of the CENPJ gene has been strongly associated with autosomal recessive primary microcephaly with or without clinical features of S eckel syndrome. In summary, although additional studies are required to fully es tablish its clinical significance, this variant meets criteria to be classified as likely pathogenic for autosomal recessive primary microcephaly with or withou t clinical features of Seckel syndrome.
