Genes affected

CEP152 (HGNC:29298): (centrosomal protein 152) This gene encodes a protein that is thought to be involved with centrosome function. Mutations in this gene have been associated with primary microcephaly (MCPH4). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2010]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.147 CDS is truncated, and there are 0 pathogenic variants in the truncated region.
• BP6: Variant 15-48739002-AAC-A is Benign according to our data. Variant chr15-48739002-AAC-A is described in ClinVar as [Likely_benign]. Clinvar id is 31033.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr15-48739002-AAC-A is described in Lovd as [Pathogenic].
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00412 (628/152330) while in subpopulation AFR AF= 0.0146 (608/41576). AF 95% confidence interval is 0.0137. There are 3 homozygotes in gnomad4. There are 284 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 3 AR gene
