Genes affected

MAX (HGNC:6913): (MYC associated factor X) The protein encoded by this gene is a member of the basic helix-loop-helix leucine zipper (bHLHZ) family of transcription factors. It is able to form homodimers and heterodimers with other family members, which include Mad, Mxi1 and Myc. Myc is an oncoprotein implicated in cell proliferation, differentiation and apoptosis. The homodimers and heterodimers compete for a common DNA target site (the E box) and rearrangement among these dimer forms provides a complex system of transcriptional regulation. Mutations of this gene have been reported to be associated with hereditary pheochromocytoma. A pseudogene of this gene is located on the long arm of chromosome 7. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.R100C variant (also known as c.298C>T), located in coding exon 5 of the MAX gene, results from a C to T substitution at nucleotide position 298. The arginine at codon 100 is replaced by cysteine, an amino acid with highly dissimilar properties. This alteration was detected in 1/102 Asian children diagnosed with a tumor under the age of 18 who underwent whole exome sequencing (Chan SH et al, NPJ Genom Med. 2018 Nov;3:30). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 100 of the MAX protein (p.Arg100Cys). This variant is present in population databases (rs762084527, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with MAX-related conditions. ClinVar contains an entry for this variant (Variation ID: 404108). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
