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.

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2022The c.230G>A (p.S77N) alteration is located in exon 2 (coding exon 2) of the THG1L gene. This alteration results from a G to A substitution at nucleotide position 230, causing the serine (S) at amino acid position 77 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
