Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.460G>A (p.A154T) alteration is located in exon 2 (coding exon 2) of the DDN gene. This alteration results from a G to A substitution at nucleotide position 460, causing the alanine (A) at amino acid position 154 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
