Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 18, 2021The c.1462G>A (p.D488N) 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 1462, causing the aspartic acid (D) at amino acid position 488 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
