The p.V9L variant (also known as c.25G>T), located in coding exon 1 of the MAX gene, results from a G to T substitution at nucleotide position 25. The valine at codon 9 is replaced by leucine, an amino acid with highly similar properties. This variant was reported in 1 of 1694 patients with pheochromocytoma or paraganglioma; this patient was a 13 year old male with a pheochromocytoma and a thoracoabdominal paraganglioma (Burnichon N et al. Clin. Cancer Res. 2012 May; 18(10):2828-37; Comino-Méndez I et al. J. Mol. Med. 2015 Nov; 93(11):1247-55). Additionally, in a Luciferase reporter assay, the alteration MAX p.V9L was found to have a minor impact on MYC’s E-box transcriptional activation (Comino-Méndez I et al. J. Mol. Med. 2015 Nov; 93(11):1247-55). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
