Genes affected
TST (HGNC:12388): (thiosulfate sulfurtransferase) This is one of two neighboring genes encoding similar proteins that each contain two rhodanese domains. The encoded protein is localized to the mitochondria and catalyzes the conversion of thiosulfate and cyanide to thiocyanate and sulfite. In addition, the protein interacts with 5S ribosomal RNA and facilitates its import into the mitochondria. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 05, 2022The c.557G>A (p.G186E) alteration is located in exon 2 (coding exon 1) of the TST gene. This alteration results from a G to A substitution at nucleotide position 557, causing the glycine (G) at amino acid position 186 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
