Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.205C>A (p.R69S) alteration is located in exon 1 (coding exon 1) of the DDN gene. This alteration results from a C to A substitution at nucleotide position 205, causing the arginine (R) at amino acid position 69 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
