This variant is denoted MAX c.25G>T at the cDNA level, p.Val9Leu (V9L) at the protein level, and results in the change of a Valine to a Leucine (GTG>TTG). This variant was has been reported in one individual with bilateral pheochromocytoma and in another individual with both a pheochromocytoma and paraganglioma (Burnichon 2012, Menara 2015). However, loss of heterozygosity (LOH) was not detected in the tumor of one of the individuals for which LOH was performed (Burnichon 2012). A luciferase reporter assay showed that this variant is unable to fully repress MYC activity compared to wildtype (Comino-Mendex 2015). MAX Val9Leu was observed at an allele frequency of 0.05% in individuals of Finnish ancestry in large population cohorts (Lek 2016). This variant is not located in a known functional domain. In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function. Based on currently available evidence, it is unclear whether MAX Val9Leu is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
