Genes affected
ADAD1 (HGNC:30713): (adenosine deaminase domain containing 1) Predicted to enable double-stranded RNA adenosine deaminase activity; double-stranded RNA binding activity; and tRNA-specific adenosine deaminase activity. Predicted to be involved in RNA processing and adenosine to inosine editing. Predicted to act upstream of or within spermatid development. Predicted to be located in nucleus. Predicted to be active in cytoplasm and nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
