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 -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0023153126).

BP6

Variant 4-55981275-G-A is Benign according to our data. Variant chr4-55981275-G-A is described in ClinVar as Benign. ClinVar VariationId is 128694.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0106 (1605/152090) while in subpopulation AFR AF = 0.0371 (1537/41476). AF 95% confidence interval is 0.0355. There are 29 homozygotes in GnomAd4. There are 764 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 29 AR gene
