Genes affected

SLC25A30 (HGNC:27371): (solute carrier family 25 member 30) Although the outer mitochondrial membrane is permeable to many small metabolites, transport of solutes across the inner mitochondrial membrane is achieved by members of the mitochondrial carrier protein family, such as SLC25A30 (Haguenauer et al., 2005 [PubMed 15809292]).[supplied by OMIM, Mar 2008]

Collection Method: clinical testing

The c.149G>A (p.R50Q) alteration is located in exon 3 (coding exon 2) of the SLC25A30 gene. This alteration results from a G to A substitution at nucleotide position 149, causing the arginine (R) at amino acid position 50 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
