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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.00822556).

BP6

Variant 4-56017835-C-T is Benign according to our data. Variant chr4-56017835-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 128701.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00315 (479/152266) while in subpopulation AFR AF = 0.0107 (443/41554). AF 95% confidence interval is 0.00984. There are 3 homozygotes in GnomAd4. There are 248 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 3 AR gene
