Genes affected
CEP120 (HGNC:26690): (centrosomal protein 120) This gene encodes a protein that functions in the microtubule-dependent coupling of the nucleus and the centrosome. A similar protein in mouse plays a role in both interkinetic nuclear migration, which is a characteristic pattern of nuclear movement in neural progenitors, and in neural progenitor self-renewal. Mutations in this gene are predicted to result in neurogenic defects. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0072216988).
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00396 (584/147584) while in subpopulation NFE AF= 0.00473 (318/67268). AF 95% confidence interval is 0.0043. There are 1 homozygotes in gnomad4. There are 326 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 22 AR gene
