Case report : A novel variant in SLC25A46 causing sensorimotor polyneuropathy and optic atrophy
Copyright © 2022 Kodal, Hammer-Hansen, Holm-Yildiz, Grønskov, Karstensen and Dysgaard..
SLC25A46 is a mitochondrial protein involved in mitochondrial dynamics. Recently, bi-allelic variants have been identified as a pathogenic cause in a spectrum of neurological syndromes. We report a novel homozygous SLC25A46 variant in two siblings, originating from Iraq. Both presented with optic atrophy and varying neurological symptoms. The neurological examination and nerve conduction studies were consistent with sensorimotor polyneuropathy, one having mild polyneuropathy and the other pronounced polyneuropathy. The cases illustrate the disease spectrum and provide substantial information to the knowledge of polyneuropathy caused by SLC25A46 variants. It further highlights the diagnostic potentials of whole exome sequencing which can improve future understanding of disease mechanisms.
