Genes affected
PARG (HGNC:8605): (poly(ADP-ribose) glycohydrolase) Poly(ADP-ribose) glycohydrolase (PARG) is the major enzyme responsible for the catabolism of poly(ADP-ribose), a reversible covalent-modifier of chromosomal proteins. The protein is found in many tissues and may be subject to proteolysis generating smaller, active products. Several transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2023The c.1991T>C (p.L664S) alteration is located in exon 10 (coding exon 10) of the PARG gene. This alteration results from a T to C substitution at nucleotide position 1991, causing the leucine (L) at amino acid position 664 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
