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.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant, c.938_940del, results in the deletion of 1 amino acid(s) of the SLC25A46 protein (p.Tyr313del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs768345785, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with SLC25A46-related conditions. ClinVar contains an entry for this variant (Variation ID: 644999). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Collection Method:clinical testing

The c.938_940delATT variant (also known as p.Y313del) is located in coding exon 8 of the SLC25A46 gene. This variant results from an in-frame ATT deletion at nucleotide positions 938 to 940. This results in the in-frame deletion of a tyrosine at codon 313. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis (Choi Y et al. PLoS ONE. 2012; 7(10):e46688). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
