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.

Ambry Genetics

Feb 14, 2023

The c.370G>A (p.V124I) 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 370, causing the valine (V) at amino acid position 124 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
