Genes affected

SLC25A46 (HGNC:25198): (solute carrier family 25 member 46) This gene encodes a mitochondrial solute carrier protein family member. It functions in promoting mitochondrial fission, and prevents the formation of hyperfilamentous mitochondria. Mutation of this gene results in neuropathy and optic atrophy.

Collection Method:clinical testing

The c.235G>C (p.E79Q) alteration is located in exon 1 (coding exon 1) of the SLC25A46 gene. This alteration results from a G to C substitution at nucleotide position 235, causing the glutamic acid (E) at amino acid position 79 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
