Genes affected
SQOR (HGNC:20390): (sulfide quinone oxidoreductase) The protein encoded by this gene may function in mitochondria to catalyze the conversion of sulfide to persulfides, thereby decreasing toxic concencrations of sulfide. Alternative splicing results in multiple transcript variants that encode the same protein. [provided by RefSeq, Sep 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 11, 2023The c.301C>T (p.R101C) alteration is located in exon 3 (coding exon 2) of the SQRDL gene. This alteration results from a C to T substitution at nucleotide position 301, causing the arginine (R) at amino acid position 101 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
