Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 18, 2023The c.215G>A (p.G72E) alteration is located in exon 1 (coding exon 1) of the ADAD2 gene. This alteration results from a G to A substitution at nucleotide position 215, causing the glycine (G) at amino acid position 72 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
