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]

Nov 15, 2023

The c.127A>T (p.T43S) alteration is located in exon 3 (coding exon 2) of the CEP135 gene. This alteration results from a A to T substitution at nucleotide position 127, causing the threonine (T) at amino acid position 43 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
