Genes affected

AGBL4 (HGNC:25892): (AGBL carboxypeptidase 4) Predicted to enable metallocarboxypeptidase activity and tubulin binding activity. Predicted to be involved in C-terminal protein deglutamylation; defense response to virus; and protein side chain deglutamylation. Predicted to act upstream of or within several processes, including axonal transport of mitochondrion; positive regulation of ubiquitin-dependent protein catabolic process; and regulation of blastocyst development. Located in Golgi apparatus; centriole; and ciliary basal body. [provided by Alliance of Genome Resources, Apr 2022]

The c.808A>T (p.N270Y) alteration is located in exon 8 (coding exon 8) of the AGBL4 gene. This alteration results from a A to T substitution at nucleotide position 808, causing the asparagine (N) at amino acid position 270 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
