Invitae RCV000465673 SCV000546027 uncertain significance Gastrointestinal stroma tumor; Paragangliomas 3 2018-12-28 criteria provided, single submitter clinical testing This sequence change falls in intron 1 of the SDHC gene. It does not directly change the encoded amino acid sequence of the SDHC protein, but it affects a nucleotide within the consensus splice site of the intron. This variant is present in population databases (rs377566366, ExAC 0.01%) but has not been reported in the literature in individuals with a SDHC-related disease. Nucleotide substitutions within the consensus splice site are relatively common causes of aberrant splicing (PMID: 17576681, 9536098) but according to multiple splice site algorithms this particular variant is not predicted to significantly affect splicing. These predictions have not been confirmed by published functional studies. In summary, this is a novel intronic change with uncertain impact on splicing. It has been classified as a Variant of Uncertain Significance.
