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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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. -

Variant summary: AEBP1 c.37C>T (p.Leu13Phe) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 6.7e-05 in 224010 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in AEBP1 causing Ehlers-Danlos syndrome, classic-like, 2 (6.7e-05 vs 0.0011), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.37C>T in individuals affected with Ehlers-Danlos syndrome, classic-like, 2 and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 1482894). Based on the evidence outlined above, the variant was classified as uncertain significance. -
