The SDHC c.439C>T; p.Gln147Ter variant is reported in the medical literature in an individual with paraganglioma (Schiavi 2005, Schiavi 2006). This variant is absent from general population databases (Exome Variant Server, Genome Aggregation Database), indicating it is not a common polymorphism. This variant results in a premature termination codon in the last exon of the SDHC gene. While this may not lead to nonsense-mediated decay, it is expected to create a truncated SDHC protein. Based on available information, this variant is considered to be likely pathogenic. References: Schiavi F et al. Predictors and prevalence of paraganglioma syndrome associated with mutations of the SDHC gene. JAMA. 2005 Oct 26;294(16):2057-63. Schiavi F et al.
