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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2023The c.1430G>A (p.R477Q) alteration is located in exon 14 (coding exon 14) of the AGBL4 gene. This alteration results from a G to A substitution at nucleotide position 1430, causing the arginine (R) at amino acid position 477 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
