Genes affected
AGBL5 (HGNC:26147): (AGBL carboxypeptidase 5) This gene encodes a metallocarboxypeptidase involved in protein deglutamylation and a member of the peptidase M14 family of proteins. The encoded protein has been described as a "dual-functional" deglutamylase that can remove glutamate residues from both carboxyl termini and side chains of protein substrates. This deglutamylase activity may be important in antiviral immunity. Mutations in this gene are associated with retinitis pigmentosa. [provided by RefSeq, Jul 2016]

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 295 of the AGBL5 protein (p.Asp295Asn). This variant is present in population databases (no rsID available, gnomAD 0.003%). This missense change has been observed in individuals with retinitis pigmentosa (PMID: 26720455; internal data). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 242932). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. This variant disrupts the p.Asp295His amino acid residue in AGBL5. Other variant(s) that disrupt this residue have been observed in individuals with AGBL5-related conditions (internal data), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. -
