Genes affected

ADPRS (HGNC:21304): (ADP-ribosylserine hydrolase) This gene encodes a member of the ADP-ribosylglycohydrolase family. The encoded enzyme catalyzes the removal of ADP-ribose from ADP-ribosylated proteins. This enzyme localizes to the mitochondria, in addition to the nucleus and cytoplasm.[provided by RefSeq, Feb 2009]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-36089049-AC-A is Pathogenic according to our data. Variant chr1-36089049-AC-A is described in ClinVar as [Pathogenic]. Clinvar id is 2572385.Status of the report is criteria_provided_single_submitter, 1 stars.

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The variant is not observed in the gnomAD v2.1.1 dataset. The variant is predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant. Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline. -
