Genes affected

FOXRED1 (HGNC:26927): (FAD dependent oxidoreductase domain containing 1) This gene encodes a protein that contains a FAD-dependent oxidoreductase domain. The encoded protein is localized to the mitochondria and may function as a chaperone protein required for the function of mitochondrial complex I. Mutations in this gene are associated with mitochondrial complex I deficiency. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Dec 2010]

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 25, 2024	This sequence change creates a premature translational stop signal (p.Ala206Serfs*15) in the FOXRED1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in FOXRED1 are known to be pathogenic (PMID: 20818383, 20858599). This variant is present in population databases (rs765593341, gnomAD 0.07%). This premature translational stop signal has been observed in individuals with mitochondrial complex I deficiency (PMID: 22200994, 31065540). ClinVar contains an entry for this variant (Variation ID: 95754). For these reasons, this variant has been classified as Pathogenic. -

The Ala206SerfsX15 variant has been identified in 0.012% (1/8254) of European American chromosomes and 0.023% (1/4264) of African American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/). The same frameshift variant (but from a different nucleotide variant) in FOXRED1 has been reported in 1 individual with mitochondrial complex I deficiency (Haack 2012). This individual was compound heterozygous. The Ala206SerfsX15 frameshift variant is predicted to alter the protein’s amino acid sequence beginning at position 206 and lead to a premature termination codon 15 amino acids downstream. This alteration is then predicted to lead to a truncated or absent protein. In summary, this variant is likely to be pathogenic, though additional data are required to fully establish the role of the FOXRED1 gene in disease given limited studies to date. -

The c.612_615dupAGTG (p.A206Sfs*15) alteration, located in exon 5 (coding exon 5) of the FOXRED1 gene, consists of a duplication of AGTG at position 612, causing a translational frameshift with a predicted alternate stop codon after 15 amino acids. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. This alteration has been detected with another mutation in patients with FOXRED1-related mitochondrial complex I deficiency (Ahmed, 2017; Apatean, 2019; Haack, 2012). Based on the available evidence, this alteration is classified as pathogenic. -

The c.612_615dup;p.(Ala206Serfs*15) is a null frameshift variant (NMD) in the FOXRED1 gene and predicts alteration of the nonsense-mediate decay - NMD is present in a relevantexon to the transcript -PVS1. This sequence change has been observed in affected individual(s) and ClinVar contains an entry for this variant (ClinVar ID: 95754; PMID: 33613441; 31065540; 22200994; 30723688; 30956948; 31589614) - PS4. The variant is present at low allele frequencies population databases (rs398124308– gnomAD 0.01314%; ABraOM 0.000427 frequency - http://abraom.ib.usp.br/) - PM2_supporting. The p.(Ala206Serfs*15) was detected in trans with a pathogenic variant(PMID: 22200994, 30723688, 31065540) - PM3. In summary, the currently available evidence indicates that the variant is pathogenic. -

Variant summary: The FOXRED1 c.612_615dupAGTG (p.Ala206Serfs) variant results in a premature termination codon, predicted to cause a truncated or absent FOXRED1 protein due to nonsense mediated decay (NMD), which are commonly known mechanisms for disease. If NMD is escaped, this variant is predicted to truncate Glycine/D-amino acid oxidase domain. Truncation downstream of this position has also been reported (PMID: 20818383). This variant was found in 24/120958 control chromosomes at a frequency of 0.0001984, which does not exceed the estimated maximal expected allele frequency of a pathogenic FOXRED1 variant (0.00125). This variant has been reported in literature in one patient with mitochondrial complex I deficiency in compound heterozygous state with p.R136W variant. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely pathogenic/pathogenic. Taken together, this variant is classified as Pathogenic. -
