Description

The p.P56L variant (also known as c.167C>T), located in coding exon 2 of the SDHB gene, results from a C to T substitution at nucleotide position 167. The proline at codon 56 is replaced by leucine, an amino acid with similar properties. This variant was reported in multiple individuals with features consistent with SDHB-related paraganglioma-pheochromocytoma syndrome (Benn DE et al. J Clin Endocrinol Metab, 2006 Mar;91:827-36; Burnichon N et al. J Clin Endocrinol Metab, 2009 Aug;94:2817-27). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this alteration remains unclear.
