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: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The MAX c.406G>A (p.Gly136Arg) missense change has a maximum subpopulation frequency of 0.096% in gnomAD v2.1.1 (BS1; https://gnomad.broadinstitute.org/variant/14-65543271-C-T). This is higher than expected for a pathogenic variant predisposing to hereditary paraganglioma-pheochromocytoma syndrome (PMID: 20301715). In silico tools are not in agreement about the effect of this variant on protein function, but to our knowledge these predictions have not been confirmed by functional assays. To our knowledge, this variant has not been reported in individuals with paraganglioma or pheochromocytoma. In summary, this variant meets criteria to be classified as likely benign based on the ACMG/AMP criteria: BS1. -
