Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2023The c.289G>A (p.D97N) alteration is located in exon 3 (coding exon 3) of the TMED8 gene. This alteration results from a G to A substitution at nucleotide position 289, causing the aspartic acid (D) at amino acid position 97 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
