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 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2024The c.799G>C (p.V267L) alteration is located in exon 8 (coding exon 6) of the ADAD1 gene. This alteration results from a G to C substitution at nucleotide position 799, causing the valine (V) at amino acid position 267 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
