NM_003001.5:c.215G>T
Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM1PM2PM5PP3_StrongPP5_Moderate
The NM_003001.5(SDHC):c.215G>T(p.Arg72Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R72G) has been classified as Likely pathogenic.

The p.R72L pathogenic mutation (also known as c.215G>T), located in coding exon 4 of the SDHC gene, results from a G to T substitution at nucleotide position 215. The arginine at codon 72 is replaced by leucine, an amino acid with dissimilar properties. This mutation has been detected in an individual with a paraganglioma (Ambry internal data). Another alteration at the same codon, p.R72H (c.215G>A), has been described in multiple individuals with a paraganglioma (Burnichon N et al. J Clin Endocrinol Metab, 2009 Aug;94:2817-27; Buffet A et al. Horm Metab Res, 2012 May;44:359-66; Gupta S et al. Endocr Pathol, 2016 Sep;27:243-52). Based on internal structural analysis, p.R72L disrupts the catalytic function of succinate dehydrogenase, via impacts on quinone binding and/or reduction to quinol (Sun F et al. Cell, 2005 Jul;121:1043-57; Lemarie A et al. Mitochondrion, 2009 Jul;9:254-60; Kluckova K et al. Cell Death Dis, 2015 May;6:e1749). 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. -
