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]

The c.50A>C (p.D17A) alteration is located in exon 2 (coding exon 1) of the CEP135 gene. This alteration results from a A to C substitution at nucleotide position 50, causing the aspartic acid (D) at amino acid position 17 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
