Genes affected

SLC25A39 (HGNC:24279): (solute carrier family 25 member 39) This gene encodes a member of the SLC25 transporter or mitochondrial carrier family of proteins. Members of this family are encoded by the nuclear genome while their protein products are usually embedded in the inner mitochondrial membrane and exhibit wide-ranging substrate specificity. Although the encoded protein is currently considered an orphan transporter, this protein is related to other carriers known to transport amino acids. This protein may play a role in iron homeostasis.

The c.847C>T (p.R283C) alteration is located in exon 10 (coding exon 9) of the SLC25A39 gene. This alteration results from a C to T substitution at nucleotide position 847, causing the arginine (R) at amino acid position 283 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
