Submissions by phenotype
Glycine encephalopathy Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | 3billion | Sep 01, 2022 | The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: <0.001%). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.83; 3Cnet: 0.94). Therefore, this variant is classified as uncertain significance according to the recommendation of ACMG/AMP guideline. - |
