Genes affected
THG1L (HGNC:26053): (tRNA-histidine guanylyltransferase 1 like) The protein encoded by this gene is a mitochondrial protein that is induced by high levels of glucose and is associated with diabetic nephropathy. The encoded protein appears to increase mitochondrial biogenesis, which could lead to renal fibrosis. Another function of this protein is that of a guanyltransferase, adding GMP to the 5' end of tRNA(His). Several transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 14, 2023The c.517C>T (p.L173F) alteration is located in exon 3 (coding exon 3) of the THG1L gene. This alteration results from a C to T substitution at nucleotide position 517, causing the leucine (L) at amino acid position 173 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
