SLC25A11 and neoplasm: Whole-exome sequencing (WES) of paired blood and tumor samples, conducted to explore the genetic etiology of CSS, revealed a novel heterozygous germline variant (c.293G>A/p.R98H) in the solute carrier family 25 member 11 (SLC25A11) gene, which encodes the mitochondrial 2-oxoglutarate/malate carrier protein.
