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]

Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 06, 2023In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. ClinVar contains an entry for this variant (Variation ID: 1347951). This variant has not been reported in the literature in individuals affected with CEP135-related conditions. This variant is present in population databases (rs780365984, gnomAD 0.02%). This sequence change affects codon 38 of the CEP135 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the CEP135 protein. It affects a nucleotide within the consensus splice site. -
