Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2023The c.1013A>G (p.H338R) alteration is located in exon 10 (coding exon 10) of the TRMT13 gene. This alteration results from a A to G substitution at nucleotide position 1013, causing the histidine (H) at amino acid position 338 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
