Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 17, 2023The c.1208G>A (p.S403N) alteration is located in exon 10 (coding exon 8) of the ADAD1 gene. This alteration results from a G to A substitution at nucleotide position 1208, causing the serine (S) at amino acid position 403 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
