Genes affected

SLC25A37 (HGNC:29786): (solute carrier family 25 member 37) SLC25A37 is a solute carrier localized in the mitochondrial inner membrane. It functions as an essential iron importer for the synthesis of mitochondrial heme and iron-sulfur clusters (summary by Chen et al., 2009 [PubMed 19805291]).[supplied by OMIM, Jan 2011]

The c.596G>A (p.R199Q) alteration is located in exon 4 (coding exon 4) of the SLC25A37 gene. This alteration results from a G to A substitution at nucleotide position 596, causing the arginine (R) at amino acid position 199 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
