Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 10, 2023The c.1522C>T (p.R508W) alteration is located in exon 12 (coding exon 10) of the ADAD1 gene. This alteration results from a C to T substitution at nucleotide position 1522, causing the arginine (R) at amino acid position 508 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
