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]

The c.907G>A (p.V303I) alteration is located in exon 7 (coding exon 6) of the SQRDL gene. This alteration results from a G to A substitution at nucleotide position 907, causing the valine (V) at amino acid position 303 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
