Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 18, 2023The c.447T>G (p.D149E) alteration is located in exon 6 (coding exon 6) of the TRMT13 gene. This alteration results from a T to G substitution at nucleotide position 447, causing the aspartic acid (D) at amino acid position 149 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
