Genes affected

SLC25A16 (HGNC:10986): (solute carrier family 25 member 16) This gene encodes a protein that contains three tandemly repeated mitochondrial carrier protein domains. The encoded protein is localized in the inner membrane and facilitates the rapid transport and exchange of molecules between the cytosol and the mitochondrial matrix space. This gene has a possible role in Graves' disease. [provided by RefSeq, Jul 2008]

The c.683C>T (p.P228L) alteration is located in exon 7 (coding exon 7) of the SLC25A16 gene. This alteration results from a C to T substitution at nucleotide position 683, causing the proline (P) at amino acid position 228 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
