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

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.81).

BP6

Variant 15-48772697-G-C is Benign according to our data. Variant chr15-48772697-G-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 158230.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000151 (23/152232) while in subpopulation EAS AF = 0.00406 (21/5178). AF 95% confidence interval is 0.00272. There are 0 homozygotes in GnomAd4. There are 17 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR gene
