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]

This sequence change creates a premature translational stop signal (p.Cys581*) in the AEBP1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in AEBP1 are known to be pathogenic (PMID: 29606302). This variant is present in population databases (rs777647845, gnomAD 0.0008%). This premature translational stop signal has been observed in individual(s) with Ehlers-Danlos syndrome (PMID: 29606302). ClinVar contains an entry for this variant (Variation ID: 545022). For these reasons, this variant has been classified as Pathogenic.
