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 -10 ACMG points.

• BP6: Variant 15-48805535-C-CTT is Benign according to our data. Variant chr15-48805535-C-CTT is described in ClinVar as [Benign]. Clinvar id is 1270486.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0119 (1322/111476) while in subpopulation AMR AF= 0.0325 (366/11268). AF 95% confidence interval is 0.0297. There are 22 homozygotes in gnomad4. There are 667 alleles in male gnomad4 subpopulation. Median coverage is 26. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 22 AR gene
