RCV000285420 | SCV002600077 | benign | Arginine:glycine amidinotransferase deficiency | 2022-06-06 | reviewed by expert panel | curation | The NM_001482.3:c.*847G>A variant is a single nucleotide substitution in the 3'UTR of GATM. Because the variant is located in the 3'UTR, it is not expected to alter the amino acid sequence. The highest population minor allele frequency in gnomAD v2.1.1 is 0.01493 (130/8702 alleles) in the African population, which is higher than the ClinGen CCDS VCEP’s threshold for BA1 (>0.0005), and therefore meets this criterion (BA1). There is a ClinVar entry for this variant (Variation ID: 316202). In summary, this variant meets the criteria to be classified as benign for AGAT deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen Cerebral Creatine Deficiency Syndromes Variant Curation Expert Panel (Specifications Version 1.1.0): BA1. (Classification approved by the ClinGen CCDS VCEP on June 6, 2022). |

RCV000285420 | SCV000391415 | benign | Arginine:glycine amidinotransferase deficiency | 2018-01-12 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. |
