Invitae RCV002242572 SCV001560437 uncertain significance Carney-Stratakis syndrome; Pheochromocytoma; Paragangliomas with sensorineural hearing loss; Cowden syndrome 3 2023-11-09 criteria provided, single submitter clinical testing This sequence change affects codon 22 of the SDHD mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the SDHD protein. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SDHD-related conditions. ClinVar contains an entry for this variant (Variation ID: 1055597). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
