Genes affected

CEP135 (HGNC:29086): (centrosomal protein 135) This gene encodes a centrosomal protein, which acts as a scaffolding protein during early centriole biogenesis, and is also required for centriole-centriole cohesion during interphase. Mutations in this gene are associated with autosomal recessive primary microcephaly-8. [provided by RefSeq, Jun 2012]

Dec 12, 2022

The c.268A>G (p.M90V) alteration is located in exon 3 (coding exon 2) of the CEP135 gene. This alteration results from a A to G substitution at nucleotide position 268, causing the methionine (M) at amino acid position 90 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
