Description

The p.R230C pathogenic mutation (also known as c.688C>T), located in coding exon 7 of the SDHB gene, results from a C to T substitution at nucleotide position 688. The arginine at codon 230 is replaced by cysteine, an amino acid with highly dissimilar properties. This pathogenic variant has been reported in numerous individuals diagnosed with pheochromocytomas and/or paragangliomas (Gimenez-Roqueplo AP et al. Cancer Res. 2003 Sep 1;63(17):5615-21; Dahia PL et al. PLoS Genet. 2005 Jul;1(1):72-80; Neumann HP et al. Cancer Res. 2009 Apr 15;69(8):3650-6; Sevilla MA et al. Otolaryngol Head Neck Surg. 2009 May;140(5):724-9; Burnichon N et al. J Clin Endocrinol Metab. 2009 Aug;94(8):2817-27; Yang C et al. FASEB J. 2012 Nov;26(11):4506-16; Andrews KA et al. J. Med. Genet. 2018 Jun;55:384-394). Additionally, two disease-causing variants, p.R230H and p.R230L, have been described in the same codon. 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 supporting evidence, this alteration is interpreted as a disease-causing mutation.
