Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 04, 2022The c.116G>C (p.R39T) alteration is located in exon 1 (coding exon 1) of the TRMT13 gene. This alteration results from a G to C substitution at nucleotide position 116, causing the arginine (R) at amino acid position 39 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
