Genes affected

AGBL1 (HGNC:26504): (AGBL carboxypeptidase 1) Polyglutamylation is a reversible posttranslational modification catalyzed by polyglutamylases that results in the addition of glutamate side chains on the modified protein. This gene encodes a glutamate decarboxylase that catalyzes the deglutamylation of polyglutamylated proteins. Mutations in this gene result in dominant late-onset Fuchs corneal dystrophy.

The c.602G>T (p.C201F) alteration is located in exon 7 (coding exon 6) of the AGBL1 gene. This alteration results from a G to T substitution at nucleotide position 602, causing the cysteine (C) at amino acid position 201 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
