The SDHD c.342T>A; p.Tyr114Ter variant is reported in the literature in multiple individuals affected with paragangliomas (Andrews 2018, Timmers 2008). This variant is reported as pathogenic by multiple laboratories in ClinVar (Variation ID: 438437), and is absent from general population databases (1000 Genomes Project, Exome Variant Server, and Genome Aggregation Database), indicating it is not a common polymorphism. This variant results in a premature termination codon in the last exon of the SDHD gene. While this may not lead to nonsense-mediated decay, it is expected to create a truncated protein missing the last 46 amino acids. Based on available information, the p.Tyr114Ter variant is considered to be pathogenic. References: Andrews KA et al.
