Pittsburgh Clinical Genomics Laboratory, University of Pittsburgh Medical Center RCV004784949 SCV005397223 uncertain significance Dystonia 24 2022-08-26 criteria provided, single submitter clinical testing This sequence variant is a single nucleotide substitution (G>A) at coding nucleotide 2191 of the ANO3 gene that results in an aspartic acid to asparagine amino acid change at residue 731 of the ANO3 protein. This novel variant is not found in an online database of clinically annotated variants (ClinVar) and has not been observed in individuals with an ANO3-disorder in the published literature, to our knowledge. This variant is absent from the gnomAD control population dataset (0 of approximately 250,000 alleles). Multiple bioinformatic tools predict that this aspartic acid to asparagine amino acid change would be tolerated, though the Asp731 residue is strongly conserved across the vertebrate species examined. Studies examining the functiol consequence of this variant have not been published, to our knowledge. At this time, there is insufficient evidence to determine if this variant is pathogenic or benign. Therefore, we consider this a variant of uncertain significance. ACMG Criteria: BP4, PM2
