Genes affected

AEBP1 (HGNC:303): (AE binding protein 1) This gene encodes a member of carboxypeptidase A protein family. The encoded protein may function as a transcriptional repressor and play a role in adipogenesis and smooth muscle cell differentiation. Studies in mice suggest that this gene functions in wound healing and abdominal wall development. Overexpression of this gene is associated with glioblastoma. [provided by RefSeq, May 2013]

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 0.041415013 fraction of the gene. Cryptic splice site detected, with MaxEntScore 4.4, offset of 36, new splice context is: gagGTgggg. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.

PM2

This variant is present in population databases (rs369016031, gnomAD 0.01%). For these reasons, this variant has been classified as 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: 545021). Disruption of this splice site has been observed in individual(s) with clinical features of AEBP1-related conditions (PMID: 27023906). It has also been observed to segregate with disease in related individuals. This sequence change affects a donor splice site in intron 13 of the AEBP1 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 AEBP1 are known to be pathogenic (PMID: 29606302). -
