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_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.037457526).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000328 (50/152242) while in subpopulation AFR AF= 0.00118 (49/41570). AF 95% confidence interval is 0.000916. There are 0 homozygotes in gnomad4. There are 25 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Sep 24, 2021	This sequence change replaces leucine with phenylalanine at codon 13 of the AEBP1 protein (p.Leu13Phe). The leucine residue is weakly conserved and there is a small physicochemical difference between leucine and phenylalanine. This variant is present in population databases (rs545702407, ExAC 0.2%). This variant has not been reported in the literature in individuals affected with AEBP1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Jun 03, 2024	In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
