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 -8 ACMG points.

PM4
Nonframeshift variant in NON repetitive region in NM_025009.5. Strenght limited to Supporting due to length of the change: 1aa.
BP6
Variant 4-55965812-AAAG-A is Benign according to our data. Variant chr4-55965812-AAAG-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 210672.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00209 (318/152346) while in subpopulation NFE AF = 0.00237 (161/68032). AF 95% confidence interval is 0.00207. There are 1 homozygotes in GnomAd4. There are 178 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 12 AR gene
