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

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.13303107).

Collection Method: clinical testing

This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with serine at codon 49 of the AEBP1 protein (p.Pro49Ser). The proline residue is weakly conserved and there is a moderate physicochemical difference between proline and serine. 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 output the following: SIFT: "Deleterious"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
