Genes affected

CEP120 (HGNC:26690): (centrosomal protein 120) This gene encodes a protein that functions in the microtubule-dependent coupling of the nucleus and the centrosome. A similar protein in mouse plays a role in both interkinetic nuclear migration, which is a characteristic pattern of nuclear movement in neural progenitors, and in neural progenitor self-renewal. Mutations in this gene are predicted to result in neurogenic defects. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

The c.2954G>A (p.S985N) alteration is located in exon 21 (coding exon 20) of the CEP120 gene. This alteration results from a G to A substitution at nucleotide position 2954, causing the serine (S) at amino acid position 985 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
