Mitochondrial disorders v8.16 SUPV3L1 Sarah Leigh changed review comment from: Three SUPV3L1 variants have been reported in two unrelated cases with a syndrome that includes ataxia, spasticity, optic atrophy and skin hypopigmentation (ASOASH) and also intellectual disability (PMID: 35023579;39596606).
The homozygous terminating SUPV3L1 variant (NM_003171.3: c.2215C>T, p.Gln739*) reported in the siblings in PMID: 35023579, was shown to results in reduced expression of the truncated protein in the proband's fibroblasts, resulting in a reduction of the mature ND6 mRNA species and also the accumulation of double-stranded RNA. This effect was partly restored using full-length SUPV3L1 cDNA (PMID: 35023579). This variant and the compound heterozygous SUPV3L1 variants (NM_003171.5: c.272-2A>G and c.1924A>C; p.(Ser642Arg) reported in PMID: 39596606 were each inherited from the parents of the proband (PMID: 35023579;39596606).
