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 made for transcript

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.025521137 fraction of the gene. Cryptic splice site detected, with MaxEntScore 3.4, offset of -1, new splice context is: aagGTtaag. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 15-48760134-C-A is Pathogenic according to our data. Variant chr15-48760134-C-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 31032.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr15-48760134-C-A is described in Lovd as [Pathogenic].

Likely pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 03, 2023In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 31032). Disruption of this splice site has been observed in individual(s) with Seckel syndrome (PMID: 21131973). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change affects a donor splice site in intron 19 of the CEP152 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in CEP152 are known to be pathogenic (PMID: 21131973). -
