Genes affected

CEP112 (HGNC:28514): (centrosomal protein 112) This gene encodes a coiled-coil domain containing protein that belongs to the cell division control protein 42 effector protein family. In neurons, it localizes to the cytoplasm of dendrites and is also enriched in the nucleus where it interacts with the RNA polymerase III transcriptional repressor Maf1 to regulate gamma-aminobutyric acid A receptor surface expression. In addition, the protein has been identified as a component of the human centrosome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2014]

Collection Method: clinical testing

The c.2714A>T (p.Q905L) alteration is located in exon 25 (coding exon 24) of the CEP112 gene. This alteration results from a A to T substitution at nucleotide position 2714, causing the glutamine (Q) at amino acid position 905 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
