Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3
The NM_017547.4(FOXRED1):c.1454T>A(p.Ile485Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000366 in 1,613,410 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. I485I) has been classified as Likely benign.

Submissions by phenotype
not provided Uncertain:2
This sequence change replaces isoleucine, which is neutral and non-polar, with asparagine, which is neutral and polar, at codon 485 of the FOXRED1 protein (p.Ile485Asn). This variant is present in population databases (rs770063137, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with FOXRED1-related conditions. ClinVar contains an entry for this variant (Variation ID: 452423). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Mitochondrial complex I deficiency, nuclear type 19 Uncertain:1

Leigh syndrome Uncertain:1
This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868]. -
Inborn genetic diseases Uncertain:1
The c.1454T>A (p.I485N) alteration is located in exon 11 (coding exon 11) of the FOXRED1 gene. This alteration results from a T to A substitution at nucleotide position 1454, causing the isoleucine (I) at amino acid position 485 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
